From e9146994cc5d5ad455f71ffaa88d17682d0301d7 Mon Sep 17 00:00:00 2001 From: Stephen Lawrence Date: Fri, 13 Mar 2026 18:36:54 +0000 Subject: [PATCH 1/9] doc site: create new Hugo doc site project using Hextra template The existing online documentation site that uses the Hugo HTML static generator and Learn template is located in /docs/docs-gen/ The project is migrating to use Hugo and the Hextra template for the doc site. The template move gives us the opportunity to update to a later Hugo version and start afresh. As a step towards that create a new Hugo project in the directory /docs/docs-site/ and enable the Hextra template.

+ +Description of Apache IoTDB from https://iotdb.apache.org/: + +*"Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for data management and analysis, deployable on the edge and the cloud. Due to its light-weight architecture, high performance and rich feature set together with its deep integration with Apache Hadoop, Spark and Flink, Apache IoTDB can meet the requirements of massive data storage, high-speed data ingestion and complex data analysis in the IoT industrial fields."* + +The IoTDB project [website](https://iotdb.apache.org/) has extensive documentation on the IoTDB server. In the guide below we focus on topics specific to the playground such as VSS data schemas and the connector for the VISSR VISS data server. + +Info: The intention is to add more information such as a guide for feeder integration as the project progresses. + +## Integrating VSS data into the IoTDB data model +The ["Background Knowledge"](https://iotdb.apache.org/UserGuide/latest/Background-knowledge/Data-Model-and-Terminology_apache.html) section of the IoTDB documentation introduces the IoTDB data model, data types, encoding and compression. + +In IoTDB terminology *measurement* is the key in a key/value pair. In VSS terms the leaf node name. The timeseries is the record of the measurement on the time axis. A timeseries is a series of time/value data points. + +The IoTDB data model supports hierarchical partitioning and like VSS uses a dot notation to separate the levels. This means if we simply appended a VSS leaf node name like `Vehicle.CurrentLocation.Longitude` as the measurement (key) name to the end of a IoTDB path such as `root.test2.dev1` IoTDB would treat the VSS path prefix `Vehicle.CurrentLocation.` as part of the IoTDB data model partitioning which could cause unwanted issues when scaling over millions of vehicles. + +We have separated those two concepts by quoting the VSS leaf node name using backticks when processing the name in IoTDB. As shown below: +``` +.`` +``` +In our example the full IoTDB measurement path would become ``root.test2.dev1.`Vehicle.CurrentLocation.Longitude` `` and in an IoTDB timeseries would look like this: +``` ++------------------------+---------------------------------------------------+ +| Time|root.test2.dev1.`Vehicle.CurrentLocation.Longitude`| ++------------------------+---------------------------------------------------+ +|2024-03-07T17:55:24.514Z| -42.4567| +|2024-04-10T17:48:12.117Z| -41.3567| +|2024-04-10T17:48:23.389Z| -39.3567| +|2024-04-10T17:48:49.630Z| -40.2578| ++------------------------+---------------------------------------------------+ + +``` + +## Seeding the database with VSS data +To illustrate the concepts lets seed a database with some simple timeseries VSS data. + +The typical steps are: +1. Create the database in the server. +2. Create a timeseries in the database populated with the VSS leaf nodes (keys) you are interested in. +3. Load the VSS data into the timeseries. + +Note: IoTDB has data type detection so creating a schema for the timeseries in step 2 is optional. However, the use of a schema has performance and meta-data benefits so is recommended. + +IoTDB has a very extensive collection of integrations, tools, clients and APIs that could be used to achieve this. + +### Example using the IoTDB CLI client +The following tutorial shows an example using the [IoTDB CLI client](https://iotdb.apache.org/UserGuide/latest/Tools-System/CLI.html), using two methods. Firstly, in interactive mode where you type the commands and then sending the same commands in batch command mode. + + +1. Connect to the CLI client from your host: +``` +$ bash /sbin/start-cli.sh -h +``` +2. Create database from CLI command line: +``` +IoTDB > create database root.test2 +``` +3. Create timeseries from CLI command line: +``` +IoTDB > CREATE ALIGNED TIMESERIES root.test2.dev1(`Vehicle.CurrentLocation.Longitude` FLOAT, `Vehicle.CurrentLocation.Latitude` FLOAT, `Vehicle.Cabin.Infotainment.HMI.DistanceUnit` TEXT) +``` +4. Add some data into the timeseries: +``` +IoTDB> insert into root.test2.dev1(`Vehicle.CurrentLocation.Longitude`, `Vehicle.CurrentLocation.Latitude`, `Vehicle.Cabin.Infotainment.HMI.DistanceUnit`) values(-42.4567, 22.1234, 'MILES') +``` +5. Display the data just added as a sanity check: +``` +IoTDB> select last * from root.test2.dev1 ++------------------------+-------------------------------------------------------------+--------+--------+ +| Time| Timeseries| Value|DataType| ++------------------------+-------------------------------------------------------------+--------+--------+ +|2024-03-07T17:55:24.514Z| root.test2.dev1.`Vehicle.CurrentLocation.Longitude`|-42.4567| FLOAT| +|2024-03-07T17:55:24.514Z|root.test2.dev1.`Vehicle.Cabin.Infotainment.HMI.DistanceUnit`| MILES| TEXT| +|2024-03-07T17:55:24.514Z| root.test2.dev1.`Vehicle.CurrentLocation.Latitude`| 22.1234| FLOAT| ++------------------------+-------------------------------------------------------------+--------+--------+ +``` +You have now seeded the database with some initial VSS data. + +The CLI client startup script accepts SQL commands using the `-e` parameter. We can therefore use this to codify the above in a bash script. So the VSS node names (keys) are passed correctly on the command line the backticks must be escaped. + +For example: +``` +# !/bin/bash + +host=127.0.0.1 +rpcPort=6667 +user=root +pass=root + +bash ./sbin/start-cli.sh -h ${host} -p ${rpcPort} -u ${user} -pw ${pass} -e "create database root.test2" + +bash ./sbin/start-cli.sh -h ${host} -p ${rpcPort} -u ${user} -pw ${pass} -e "CREATE ALIGNED TIMESERIES root.test2.dev1(\`Vehicle.CurrentLocation.Longitude\` FLOAT, \`Vehicle.CurrentLocation.Latitude\` FLOAT, \`Vehicle.Cabin.Infotainment.HMI.DistanceUnit\` TEXT)" + +bash ./sbin/start-cli.sh -h ${host} -p ${rpcPort} -u ${user} -pw ${pass} -e "insert into root.test2.dev1(\`Vehicle.CurrentLocation.Longitude\`, \`Vehicle.CurrentLocation.Latitude\`, \`Vehicle.Cabin.Infotainment.HMI.DistanceUnit\`) values(-42.4567, 22.1234, 'MILES')" + +bash ./sbin/start-cli.sh -h ${host} -p ${rpcPort} -u ${user} -pw ${pass} -e "select last * from root.test2.dev1" +``` + +Of course any of the programming language clients provided by IoTDB, e.g. go, python, C++, Rust, or integration into tools that support its SQL language, can also be used to achieve the same result. + +## Single node (Edge) vs Cluster +The upstream IoTDB project has both standalone single node and cluster deployments, to cover use case requirements from edge to cloud. + +At the time of writing the playground docker deployment deploys the single node IoTDB docker image, as it is most suitable for deployment at the edge in-vehicle, whilst still being able to represent the cloud. + +Of course if your cloud development requires higher performance then you can integrate the cluster version. + +## Data processing functions +### Built-in functions +IoTDB has an extensive collection of built-in data processing functions covering areas including: + +- Aggregate Functions, such as `SUM`. +- Arithmetic Functions, such as `SIN`. +- Comparison Functions, such as `ON_OFF`. +- String Processing Functions, such as `STRING_CONTAINS`. +- Data Type Conversion Function, such as `CAST`. +- Constant Timeseries Generating Functions, such as `CONST`. +- Selector Functions, such as `TOP_K`. +- Continuous Interval Functions, such as `ZERO_DURATION`. +- Variation Trend Calculation Functions, such as `TIME_DIFFERENCE`. +- Sampling Functions, such as `M4`. +- Change Points Function, such as `CHANGE_POINTS`. + +A full function list with examples can be found in the upstream [IoTDB Function reference manual](https://iotdb.apache.org/UserGuide/latest/SQL-Manual/Operator-and-Expression.html#_2-built-in-functions). + +### Data Quality Library functions +The IoTDB project also maintains a Data Quality Library which provides an additional collection of functions covering: +- Data Quality, such as `Completeness`. +- Data Profiling, such as `Sample`. +- Anomaly Detection, such as `Outlier`. +- Frequency Domain Analysis, such as `HighPass`. +- Data Matching, such as `Cov`. +- Data Repair, such as `TimestampRepair`. +- Series Discovery, such as `ConsecutiveSequences`. +- Machine Learning, such as `AR`. + +A full function list with examples can be found in the upstream [IoTDB UDF Data Quality Library reference manual](https://iotdb.apache.org/UserGuide/latest/SQL-Manual/UDF-Libraries_apache.html). + +#### Setup +In the upstream IoTDB project the library is an optional install. + +For your convenience it is included in the Playground IoTDB image for you. However to call the functions they must first be registered in the running IoTDB instance, which you only need to do once. The script `/iotdb/sbin/register-UDF.sh` is included in the IoTDB image to do this for you. + +Steps: + +1. Start the Playground if it is not already running. +2. From your host execute the following command to run the registration script in the IoTDB container image: + ``` + sudo docker exec -ti iotdb-service /iotdb/sbin/register-UDF.sh + ``` + + +### User Defined functions +IoTDB also allows you to integrate your own functions as User Defined Functions (UDF). The [UDF development section](https://iotdb.apache.org/UserGuide/latest/User-Manual/User-defined-function_apache.html) of the IoTDB documentation explains how to develop and register your own. + +## VISSR (VISS) integration +As part of the initial development of the playground the team extended VISSR to support connections to Apache IoTDB as a VISSR data store backend and upstreamed the support. + +### Connector scope + +The support is implemented by connector code in the VISSR service manager, which connects VISSR to an external Apache IoTDB server. This code uses the IoTDB Go client to maintain a connection session to the IoTDB server, which it then uses to get/set vehicle data from the database. + +As VISSR and the IoTDB server are separate processes VISSR needs to be told where to find the IoTDB server and which storage prefix to use to access the data. + +Development followed the patterns set by the existing VISSR support for Redis and SQLite. The administration of the Apache IoTDB server itself, including startup and shutdown, is out of scope of the connector and is handled externally to VISSR. In the case of the playground this is handled by the playground compose. + +### Runtime notes + +VISSR runtime assumptions: +1. IoTDB server lifecycle (e.g. startup and shutdown) is handled externally to VISSR. +2. Management (e.g. creation/deletion) of the IoTDB timeseries containing VSS data is handled externally to VISSR. +3. Configuration of the connector code is specified in the config file iotdb-config.json. If the config file is not found then build-time defaults are used. + +Handling of IoTDB server and timeseries management is placed outside of VISSR to allow flexible deployment through loosely coupled connections. + +### Database schema assumptions +The connector assumes a simple key/value pair schema for accessing VSS data in an IoTDB timeseries: + +1. VSS node names (keys) are backtick quoted when stored as measurement keys in the database e.g. `` `Vehicle.CurrentLocation.Longitude` ``. This is for reasons explained above in ["Integrating VSS data into the IoTDB data model"](#integrating-vss-data-into-the-iotdb-data-model) to avoid IoTDB interpreting the VSS tree path, in the example `Vehicle.CurrentLocation.`, as part of its storage path which also uses a dot notation. + +2. VSS data is stored using native (IoTDB) data types rather than strings. + +3. That the timeseries containing VSS nodes can be found using the prefix path specified in the config file. + +### Configuration +The connection code reads its runtime configuration from the JSON formatted file `iotdb-config.json` located in the vissv2server directory. You must specify all values. + +#### Configuration file format + +| Key name | Type | Description | +| --- | --- | --- +|`host`|String|Hostname or IP address of the IoTDB server| +|`port`|String|RPC port of the server. Default is 6667| +|`username`|String|Username to access the server. Default is root| +|`password`|String|Password to access the server. Default is root| +|`queryPrefixPath`|String|Timeseries prefix path of VSS data in the database| +|`queryTimeout(ms)`|Int| Query timeout in milliseconds| + + +Example `iotdb-config.json`: +``` +{ + "host": "iotdb-service", + "port": "6667", + "username": "root", + "password": "root", + "queryPrefixPath": "root.test2.dev1", + "queryTimeout(ms)": 5000 +} +``` +### Logging +The connector writes information, warning and error messages to the VISSR server log with the prefix ``IoTDB``. Grepping in the log for that prefix string can help you quickly identify connector messages. + +### VISSR Development notes +Please see the notes in the VISSR source commit messages and related Github pull requests for the history of the development of the Apache IoTDB connection code and its integration into the VISSR Service Manager component. + +Development followed the patterns set by the existing support for Redis and SQLite. + +The connection code was first developed with Apache IoTDB v1.2.2, using the upstream standalone pre-built image and Apache IoTDB Go Client v1.1.7. \ No newline at end of file diff --git a/docs/doc-site/content/docs/manuals/vissr-viss.md b/docs/doc-site/content/docs/manuals/vissr-viss.md new file mode 100644 index 00000000..90a3b3d8 --- /dev/null +++ b/docs/doc-site/content/docs/manuals/vissr-viss.md @@ -0,0 +1,11 @@ +--- +title: "VISSR (VISS data server)" +--- + +## Introduction +The playground uses the [VISSR](https://github.com/COVESA/vissr) project to provide its northbound VISS support, along with the other features it provides. + +The VISSR project [documentation site](https://covesa.github.io/vissr/) has extensive documentation on the VISSR components.

For example, in-vehicle data analysis can be performed to derive some information or knowledge and then data reduced for further processing in the cloud. + ++ As well as Native APIs IoTDB also supports a SQL-like query language.

Easy to develop: make it easy to build, modify and trial by providing a containerized instance running on a host using [Docker containers](https://www.docker.com/). +2.

From a communication and community perspective it is important to maintain descriptions of the logical concepts. Discussion at a logical level allows different parties to collaborate on common concepts, whilst making different implementation decisions, e.g. in product/technology selection or system architecture for example. That however does not mean we need spend months in philosophical discussions before moving to implementation. Instead logical concepts (why, what) can be developed alongside implementation. + +The Data Architecture team therefore intends to maintain concepts for both logical and implementation alongside each other for their projects using the playground. + +Of course it is perfectly normal that in _using_ the playground to develop an idea, example or pattern, that an architecture and components are chosen as part of the design. + +## Why _Central Data Service Playground_ ? + +### Problem +OEMs have presented various open questions and requirements in tackling growing software complexity.

They also recognized similar needs in the wider community inside and outside COVESA. For example, for COVESA to demonstrate how VSS data can be used with its eco-system for newcomers. + +The playground goals from the introductory overview: + +_The Central Data Service Playground (CDSP) serves as a neutral, open playground for data services both within and outside the vehicle in the context of data-centric architectures. It enables investigation into the internals of these services and how they can be combined. Furthermore, the playground provides a means to publish and collaborate on such work in the open._ + +The following sections address the Why, What and How in more detail. + +### Why _Central Data Service_? + ++ VSS is a mechanism of abstraction. The COVESA logical architecture for the VSS eco-system shown below places operation in the 'big ECUs', in zonal ECUs and above. Discussion of next-gen and data-centric architectures suggests investigation into data services in zone, domain and HPC controller scenarios and the cooperation between them. Hence _Central_. + +{{< figure src="/images/Logical-Architecture-Overview.drawio.svg" title="The COVESA Logical Architecture">}} + + ++ A repeating pattern of discussion in the COVESA Data Architecture team is the combination of VSS Data Server and VSS Data Store with advanced features and their connection southbound to feeders/native data and northbound to clients and off-board. Hence _Data Service_. + ++ The name Central Data Service is not an attempt to introduce a new category of component. It is used here simply as a useful synonym for what otherwise would be a longer descriptive phrase explaining combinations of VSS centric Data Server and Store and their location in the vehicle. + + ### Why _Playground_? Why not PoC? + ++ A PoC is often a snapshot in time and often specific in scope. Playground suggests greater flexibility. The central service, the Lego building block, is intended to be flexible and evolving. Similarly with what it is combined with to illustrate COVESA concepts and technology. + ++ The Playground could certainly be used to implement a PoC. + ++ Patterns such as view/controller, out of the box data servers, data stores linked to applications (e.g. SQLite) etc are well known. The Service could in part be defined by what's not known, by open questions in next-gen architectures such as data-centric architectures, that needs to be tackled down. The Playground is the means to doing that and illustrating the results. + +## What? + +### Requirements + +{{< figure src="/images/cdsp-logical-concept.drawio.svg" title="The data service core requirements" >}} + +At its core the service has requirements in three key areas: + +1. Data Models: the live data models - VSS as the abstracted view of the vehicle, along with other adjacent data models such as personal data. + +2. Persistence: history of the model and signals etc - historical and cached timeseries data. + +3. Application logic / APIs: standardized APIs for accessing the data such as the [Vehicle Information Service Specification (VISS)](https://github.com/COVESA/vehicle-information-service-specification) + or GraphQL. + +_Additional requirements:_ It is recognized that additional features, such as synchronization are absolutely desirable and have been a part of discussions in the Data Architecture team. Such features may also already be part of the feature set of the playground components. For example, both the Apache IoTDB and MongoDB Realm databases have sync capabilities. A base feature set is described as a starting point to help readers quickly grasp the concept. Additional features will be created or illustrated collectively based on interest and participation. + +### Components + +As a starting point the playground has been realized as a 'project of projects' to create the basic building block data service. Achieved by combining a VISS Data Protocol Server with highly functional VSS Data Stores. + +The VISS Protocol Server principally provides northbound get/set/sub application logic using the VISS protocol. Along with the secondary benefit of any additional features provided by the server. + +'Highly functional' in the context of the VSS Data Store means the flexible means to store, query, process and analysis timeseries data. An archetype would be a database server that can operate in-vehicle and the cloud. Such a component provides the possibility of using a variety of different architecture patterns, such as both client-server and event-driven, or data processing approaches. + +### Flexibility in use + +As well as the mentioned flexibility in implementation, flexibility in use is also intended: + ++ With some supporting documentation it can help meet the ongoing request from newcomers to the VSS eco-system as to how VSS can be used. + ++ The Data Architecture group has various topics it wishes to investigate related to data-centric architectures. Data layer topics such as sync, data reduction and data quality. Also separation of concerns and cooperation between data and knowledge layers. + ++ The playground can be used to investigate internals of data services. For example, connecting to medium and high speed data, or adding a protocol. + ++ External connections with other systems may also be a focus. For example, combining the service with other components to implement a particular touchpoint such as mobile. + +Further details can be found in the following sections. + +### The Playground in context + +To help understand its use lets quickly place the playground in context. + +**Big picture**: As stated above the COVESA logical architecture places its scope at Zonal ECUs and above as shown in the diagram. It is assumed that the playground would likely be deployed on a Zone, Domain or Central controller, with corresponding h/w capabilities. + +**Interaction between 'Large ECU'**: In the COVESA Data Architecture team it is recognized that zone/domain specific data services will need to synchronize and cooperate between themselves and/or with a central vehicle computer, e.g. Inter-controller sync/cooperation: + +![Cooperation between zonal data stores and central data service/store](https://raw.githubusercontent.com/slawr/vss-otaku/master/in-vehicle-storage/apache-iotdb/doc/zonal-vss-store-cooperation.drawio.svg "Cooperation between zonal data stores") +Source: [vss-otaku](https://github.com/slawr/vss-otaku) + +**In-vehicle southbound**: The playground can be integrated southbound to lower parts of the vehicle and its native data, through data feeders and connectors. This can include making connections to other systems such as Autosar etc. + +**Northbound**: connections will be made to clients, mobile, cloud and major in-vehicle domains such as IVI running Android/Apple etc. + +**Logical domains**: Connections may also be made to other logical data domains. For example, there is an [knowledge layer proposal](https://wiki.covesa.global/x/cYI8B) made in the COVESA Data Architecture team that discusses the separation of concerns and interaction between knowledge, information and raw data layers as illustrated below. The Playground here could be used to provide the data/information layer services in its investigation. + +![Knowledge layer proposal](https://covesa.atlassian.net/wiki/download/attachments/39065679/Knowledge-Layer-v3.png?api=v2?width=50pc "Deployment illustration from the proposal") + Source: [knowledge layer proposal](https://wiki.covesa.global/x/cYI8B) + +### Project success factors + +1. Newcomers to COVESA technology use the playground to accelerate their understanding of how the technology can be used. That could be a looking at a simple instance of how a VSS data server is combined with a VSS data store and queried using VISS. It could also be a more complex instance that combines components to illustrate a longer specific end to end use case, e.g. mobile to vehicle connection. + +2. Internal groups within COVESA naturally use the logical concepts and the playground implementation in combination with other components to develop and disseminate ideas. This especially applies to the Data Architecture and Infrastructure pillar. + +3. Supporting materials such as patterns, diagrams, cookbooks etc are adopted as useful assets within and outside COVESA, which in turn helps socialization. + +## How? + ++ Address two high level implementation needs, keeping in mind a path towards production where possible: + + - Easy to develop: make it easy to build, modify and trial by providing an instance running on a host, e.g. using Docker container(s). + + - Closer to production: the same base code should be deployable to systems closer to production, including on automotive hardware (or its simulation), e.g. Yocto, container orchestration, SOA etc. + ++ A path towards production can be supported by using production components, rather than overly simple substitutes, where it makes sense. For instance a particular scenario may use Kafka in a cloud connection. The point is not to pick a winning product in a particular category, but to recognize that using a production tool can represent a category that is known to scale. Detailed requirements for a specific production project and product selection for it, is rightly left to that project. + ++ A generic code base for the basic building blocks should allow flexible compilation to meet those needs on multiple architectures, e.g. x86, ARM and RISC-V. The target for how it is used being a matter of deployment at a high level. + ++ Follow the OSS mantra of adopt where you can, extend if needed, create where necessary. + ++ Promote flexible reconfiguration of components by favouring loose coupling over tight coupling. \ No newline at end of file diff --git a/docs/doc-site/content/docs/overview/cdsp-overview.md b/docs/doc-site/content/docs/overview/cdsp-overview.md new file mode 100644 index 00000000..e3d955e0 --- /dev/null +++ b/docs/doc-site/content/docs/overview/cdsp-overview.md @@ -0,0 +1,13 @@ +--- +title: "Introduction" +weight: 10 +--- +The Central Data Service Playground (CDSP) serves as a neutral, open playground for data services both within and outside the vehicle in the context of data-centric architectures.

-## Introduction -The playground uses Apache IoTDB to provide a highly functional data store. - -Description of Apache IoTDB from https://iotdb.apache.org/: - -*"Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for data management and analysis, deployable on the edge and the cloud. Due to its light-weight architecture, high performance and rich feature set together with its deep integration with Apache Hadoop, Spark and Flink, Apache IoTDB can meet the requirements of massive data storage, high-speed data ingestion and complex data analysis in the IoT industrial fields."* - -The IoTDB project [website](https://iotdb.apache.org/) has extensive documentation on the IoTDB server. In the guide below we focus on topics specific to the playground such as VSS data schemas and the connector for the VISSR VISS data server. - -Info: The intention is to add more information such as a guide for feeder integration as the project progresses. - -## Integrating VSS data into the IoTDB data model -The ["Background Knowledge"](https://iotdb.apache.org/UserGuide/latest/Background-knowledge/Data-Model-and-Terminology_apache.html) section of the IoTDB documentation introduces the IoTDB data model, data types, encoding and compression. - -In IoTDB terminology *measurement* is the key in a key/value pair. In VSS terms the leaf node name. The timeseries is the record of the measurement on the time axis. A timeseries is a series of time/value data points. - -The IoTDB data model supports hierarchical partitioning and like VSS uses a dot notation to separate the levels. This means if we simply appended a VSS leaf node name like `Vehicle.CurrentLocation.Longitude` as the measurement (key) name to the end of a IoTDB path such as `root.test2.dev1` IoTDB would treat the VSS path prefix `Vehicle.CurrentLocation.` as part of the IoTDB data model partitioning which could cause unwanted issues when scaling over millions of vehicles. - -We have separated those two concepts by quoting the VSS leaf node name using backticks when processing the name in IoTDB. As shown below: -``` -<IoTDB prefix path>.`<VSS leaf node name>` -``` -In our example the full IoTDB measurement path would become ``root.test2.dev1.`Vehicle.CurrentLocation.Longitude` `` and in an IoTDB timeseries would look like this: -``` -+------------------------+---------------------------------------------------+ -| Time|root.test2.dev1.`Vehicle.CurrentLocation.Longitude`| -+------------------------+---------------------------------------------------+ -|2024-03-07T17:55:24.514Z| -42.4567| -|2024-04-10T17:48:12.117Z| -41.3567| -|2024-04-10T17:48:23.389Z| -39.3567| -|2024-04-10T17:48:49.630Z| -40.2578| -+------------------------+---------------------------------------------------+ - -``` - -## Seeding the database with VSS data -To illustrate the concepts lets seed a database with some simple timeseries VSS data. - -The typical steps are: -1. Create the database in the server. -2. Create a timeseries in the database populated with the VSS leaf nodes (keys) you are interested in. -3. Load the VSS data into the timeseries. - -Note: IoTDB has data type detection so creating a schema for the timeseries in step 2 is optional. However, the use of a schema has performance and meta-data benefits so is recommended. - -IoTDB has a very extensive collection of integrations, tools, clients and APIs that could be used to achieve this. - -### Example using the IoTDB CLI client -The following tutorial shows an example using the [IoTDB CLI client](https://iotdb.apache.org/UserGuide/latest/Tools-System/CLI.html), using two methods. Firstly, in interactive mode where you type the commands and then sending the same commands in batch command mode. - - -1. Connect to the CLI client from your host: -``` -$ bash <iotdb path>/sbin/start-cli.sh -h <server hostname/ip> -``` -2. Create database from CLI command line: -``` -IoTDB > create database root.test2 -``` -3. Create timeseries from CLI command line: -``` -IoTDB > CREATE ALIGNED TIMESERIES root.test2.dev1(`Vehicle.CurrentLocation.Longitude` FLOAT, `Vehicle.CurrentLocation.Latitude` FLOAT, `Vehicle.Cabin.Infotainment.HMI.DistanceUnit` TEXT) -``` -4. Add some data into the timeseries: -``` -IoTDB> insert into root.test2.dev1(`Vehicle.CurrentLocation.Longitude`, `Vehicle.CurrentLocation.Latitude`, `Vehicle.Cabin.Infotainment.HMI.DistanceUnit`) values(-42.4567, 22.1234, 'MILES') -``` -5.

However to call the functions they must first be registered in the running IoTDB instance, which you only need to do once. The script `/iotdb/sbin/register-UDF.sh` is included in the IoTDB image to do this for you. - -Steps: - -1. Start the Playground if it is not already running. -2. From your host execute the following command to run the registration script in the IoTDB container image: - ``` - sudo docker exec -ti iotdb-service /iotdb/sbin/register-UDF.sh - ``` - - -### User Defined functions -IoTDB also allows you to integrate your own functions as User Defined Functions (UDF). The [UDF development section](https://iotdb.apache.org/UserGuide/latest/User-Manual/User-defined-function_apache.html) of the IoTDB documentation explains how to develop and register your own. - -## VISSR (VISS) integration -As part of the initial development of the playground the team extended VISSR to support connections to Apache IoTDB as a VISSR data store backend and upstreamed the support. - -### Connector scope - -The support is implemented by connector code in the VISSR service manager, which connects VISSR to an external Apache IoTDB server. This code uses the IoTDB Go client to maintain a connection session to the IoTDB server, which it then uses to get/set vehicle data from the database. - -As VISSR and the IoTDB server are separate processes VISSR needs to be told where to find the IoTDB server and which storage prefix to use to access the data. - -Development followed the patterns set by the existing VISSR support for Redis and SQLite. The administration of the Apache IoTDB server itself, including startup and shutdown, is out of scope of the connector and is handled externally to VISSR. In the case of the playground this is handled by the playground compose. - -### Runtime notes - -VISSR runtime assumptions: -1. IoTDB server lifecycle (e.g. startup and shutdown) is handled externally to VISSR. -2. Management (e.g. creation/deletion) of the IoTDB timeseries containing VSS data is handled externally to VISSR. -3. Configuration of the connector code is specified in the config file iotdb-config.json. If the config file is not found then build-time defaults are used. - -Handling of IoTDB server and timeseries management is placed outside of VISSR to allow flexible deployment through loosely coupled connections. - -### Database schema assumptions -The connector assumes a simple key/value pair schema for accessing VSS data in an IoTDB timeseries: - -1. VSS node names (keys) are backtick quoted when stored as measurement keys in the database e.g. `` `Vehicle.CurrentLocation.Longitude` ``. This is for reasons explained above in ["Integrating VSS data into the IoTDB data model"](#integrating-vss-data-into-the-iotdb-data-model) to avoid IoTDB interpreting the VSS tree path, in the example `Vehicle.CurrentLocation.`, as part of its storage path which also uses a dot notation. - -2. VSS data is stored using native (IoTDB) data types rather than strings. - -3. That the timeseries containing VSS nodes can be found using the prefix path specified in the config file. - -### Configuration -The connection code reads its runtime configuration from the JSON formatted file `iotdb-config.json` located in the vissv2server directory. You must specify all values. - -#### Configuration file format - -| Key name | Type | Description | -| --- | --- | --- -|`host`|String|Hostname or IP address of the IoTDB server| -|`port`|String|RPC port of the server. Default is 6667| -|`username`|String|Username to access the server. Default is root| -|`password`|String|Password to access the server. Default is root| -|`queryPrefixPath`|String|Timeseries prefix path of VSS data in the database| -|`queryTimeout(ms)`|Int| Query timeout in milliseconds| - - -Example `iotdb-config.json`: -``` -{ - "host": "iotdb-service", - "port": "6667", - "username": "root", - "password": "root", - "queryPrefixPath": "root.test2.dev1", - "queryTimeout(ms)": 5000 -} -``` -### Logging -The connector writes information, warning and error messages to the VISSR server log with the prefix ``IoTDB``. Grepping in the log for that prefix string can help you quickly identify connector messages. - -### VISSR Development notes -Please see the notes in the VISSR source commit messages and related Github pull requests for the history of the development of the Apache IoTDB connection code and its integration into the VISSR Service Manager component. - -Development followed the patterns set by the existing support for Redis and SQLite. - -The connection code was first developed with Apache IoTDB v1.2.2, using the upstream standalone pre-built image and Apache IoTDB Go Client v1.1.7. \ No newline at end of file diff --git a/docs/docs-gen/content/manuals/vissr-viss.md b/docs/docs-gen/content/manuals/vissr-viss.md deleted file mode 100644 index 90a3b3d8..00000000 --- a/docs/docs-gen/content/manuals/vissr-viss.md +++ /dev/null @@ -1,11 +0,0 @@ ---- -title: "VISSR (VISS data server)" ---- - -## Introduction -The playground uses the [VISSR](https://github.com/COVESA/vissr) project to provide its northbound VISS support, along with the other features it provides. - -The VISSR project [documentation site](https://covesa.github.io/vissr/) has extensive documentation on the VISSR components.

That support was upstreamed and merged. - -For the application database archetype MongoDB Realm was selected. Support for it is currently a work in progress as part of the playground project backlog. - -#### Apache IoTDB - -The Apache IoTDB [project page](https://iotdb.apache.org/) describes IoTDB as: - -_"Apache IoTDB (Database for Internet of Things) is an IoT native database with high performance for data management and analysis, deployable on the edge and the cloud. Due to its light-weight architecture, high performance and rich feature set together with its deep integration with Apache Hadoop, Spark and Flink, Apache IoTDB can meet the requirements of massive data storage, high-speed data ingestion and complex data analysis in the IoT industrial fields."_ - -The diagram below summarizes some of the features that make it an attractive addition to the playground. - -{{< figure src="Apache-IoTDB-feature-summary.drawio.svg" title="Summary of Apache IoTDB features" width=50pc >}} - -+ The focus on timeseries IoT data delivering high throughput, with low latency are a good fit with the automotive domain. The availability of a single node (Edge) server build is critical for in-vehicle investigations and is supported by the existence of a cluster build for the cloud if needed. - -+ Its support for client server, event and streaming data architectures allows for flexible operation using a single solution. - -+ It also has very wide API support that greatly enhances the pluggability of the data store into other components, whilst supporting the playground project goal of loose coupling. - -+ Similarly the wide range of integrations into other tools and frameworks, particularly the Apache big data stack, simplifies the integration of VSS and associated data into data-centric workflows. - -+ IoTDB has a wide range of built-in timeseries data processing and analysis functions covering topics such as data quality, profiling, repair, anomaly detection and series discovery. For example, in-vehicle data analysis can be performed to derive some information or knowledge and then data reduced for further processing in the cloud. - -+ As well as Native APIs IoTDB also supports a SQL-like query language. This supports the describing of work in logical terms that affords some portability to other solutions. - -## Deployment -The project is currently targeting two deployment scenarios: -1. Easy to develop: make it easy to build, modify and trial by providing a containerized instance running on a host using [Docker containers](https://www.docker.com/). -2. Closer to production: the same base code should be deployable to systems closer to production, including on automotive hardware (or its simulation), e.g. [Yocto](https://www.yoctoproject.org/), container orchestration, [Service-orientated architecture (SOA)](https://en.wikipedia.org/wiki/Service-oriented_architecture) etc. - -Docker containers are chosen to facilitate the rapid integration and/or swapping of technology options. Be it internals of the playground itself, or connection to other components. For example, users can easily integrate the playground into their own [docker compose](https://docs.docker.com/compose/) containing other components. - -#### Status -The containerized docker deployment is available. Deployment on automotive hardware is currently not but is part of the project backlog. - -### Host based Docker - -The playground provides docker compose files to deploy the playground using docker images. The deployment contains three main services, for Apache IoTDB, VISSR and Redis. - -Please see the playground docker readme.md in the source tree for details. - -The service definitions are based on the upstream compose files from the IoTDB and VISSR projects. - -### Automotive hardware - -The project will provide information as hardware deployment progresses. \ No newline at end of file diff --git a/docs/docs-gen/content/overview/cdsp-logical-concept.md b/docs/docs-gen/content/overview/cdsp-logical-concept.md deleted file mode 100644 index dd4a1c8b..00000000 --- a/docs/docs-gen/content/overview/cdsp-logical-concept.md +++ /dev/null @@ -1,147 +0,0 @@ ---- -title: "Playground logical concept" -weight: 20 ---- - -## Importance of maintaining a logical concept -COVESA is a grass roots OSS automotive alliance. From a communication and community perspective it is important to maintain descriptions of the logical concepts. Discussion at a logical level allows different parties to collaborate on common concepts, whilst making different implementation decisions, e.g. in product/technology selection or system architecture for example.

They also recognized similar needs in the wider community inside and outside COVESA.

It enables investigation into the internals of these services and how they can be combined. Furthermore, the playground provides a means to publish and collaborate on such work in the open._ - -The following sections address the Why, What and How in more detail. - -### Why _Central Data Service_? - -+ VSS is a mechanism of abstraction. The COVESA logical architecture for the VSS eco-system shown below places operation in the 'big ECUs', in zonal ECUs and above. Discussion of next-gen and data-centric architectures suggests investigation into data services in zone, domain and HPC controller scenarios and the cooperation between them. Hence _Central_. - -{{< figure src="Logical-Architecture-Overview.drawio.svg" title="The COVESA Logical Architecture" width=50pc >}} - -+ A repeating pattern of discussion in the COVESA Data Architecture team is the combination of VSS Data Server and VSS Data Store with advanced features and their connection southbound to feeders/native data and northbound to clients and off-board. Hence _Data Service_. - -+ The name Central Data Service is not an attempt to introduce a new category of component. It is used here simply as a useful synonym for what otherwise would be a longer descriptive phrase explaining combinations of VSS centric Data Server and Store and their location in the vehicle. - - ### Why _Playground_? Why not PoC? - -+ A PoC is often a snapshot in time and often specific in scope. Playground suggests greater flexibility. The central service, the Lego building block, is intended to be flexible and evolving. Similarly with what it is combined with to illustrate COVESA concepts and technology. - -+ The Playground could certainly be used to implement a PoC. - -+ Patterns such as view/controller, out of the box data servers, data stores linked to applications (e.g. SQLite) etc are well known. The Service could in part be defined by what's not known, by open questions in next-gen architectures such as data-centric architectures, that needs to be tackled down. The Playground is the means to doing that and illustrating the results. - -## What? - -### Requirements - -{{< figure src="cdsp-logical-concept.drawio.svg" title="The data service core requirements" >}} - -At its core the service has requirements in three key areas: - -1. Data Models: the live data models - VSS as the abstracted view of the vehicle, along with other adjacent data models such as personal data. - -2. Persistence: history of the model and signals etc - historical and cached timeseries data. - -3. Application logic / APIs: standardized APIs for accessing the data such as the [Vehicle Information Service Specification (VISS)](https://github.com/COVESA/vehicle-information-service-specification) - or GraphQL. - -_Additional requirements:_ It is recognized that additional features, such as synchronization are absolutely desirable and have been a part of discussions in the Data Architecture team. Such features may also already be part of the feature set of the playground components. For example, the Apache IoTDB databases have sync capabilities. A base feature set is described as a starting point to help readers quickly grasp the concept. Additional features will be created or illustrated collectively based on interest and participation. - -### Components - -As a starting point the playground has been realized as a 'project of projects' to create the basic building block data service. Achieved by combining a VISS Data Protocol Server with highly functional VSS Data Stores. - -The VISS Protocol Server principally provides northbound get/set/sub application logic using the VISS protocol. Along with the secondary benefit of any additional features provided by the server. - -'Highly functional' in the context of the VSS Data Store means the flexible means to store, query, process and analysis timeseries data. An archetype would be a database server that can operate in-vehicle and the cloud. Such a component provides the possibility of using a variety of different architecture patterns, such as both client-server and event-driven, or data processing approaches. - -### Flexibility in use - -As well as the mentioned flexibility in implementation, flexibility in use is also intended: - -+ With some supporting documentation it can help meet the ongoing request from newcomers to the VSS eco-system as to how VSS can be used. - -+ The Data Architecture group has various topics it wishes to investigate related to data-centric architectures. Data layer topics such as sync, data reduction and data quality. Also separation of concerns and cooperation between data and knowledge layers. - -+ The playground can be used to investigate internals of data services. For example, connecting to medium and high speed data, or adding a protocol. - -+ External connections with other systems may also be a focus. For example, combining the service with other components to implement a particular touchpoint such as mobile. - -Further details can be found in the following sections. - -### The Playground in context - -To help understand its use lets quickly place the playground in context. - -**Big picture**: As stated above the COVESA logical architecture places its scope at Zonal ECUs and above as shown in the diagram. It is assumed that the playground would likely be deployed on a Zone, Domain or Central controller, with corresponding h/w capabilities. - -**Interaction between 'Large ECU'**: In the COVESA Data Architecture team it is recognized that zone/domain specific data services will need to synchronize and cooperate between themselves and/or with a central vehicle computer, e.g. Inter-controller sync/cooperation: - -![Cooperation between zonal data stores and central data service/store](https://raw.githubusercontent.com/slawr/vss-otaku/master/in-vehicle-storage/apache-iotdb/doc/zonal-vss-store-cooperation.drawio.svg "Cooperation between zonal data stores") -Source: [vss-otaku](https://github.com/slawr/vss-otaku) - -**In-vehicle southbound**: The playground can be integrated southbound to lower parts of the vehicle and its native data, through data feeders and connectors. This can include making connections to other systems such as Autosar etc. - -**Northbound**: connections will be made to clients, mobile, cloud and major in-vehicle domains such as IVI running Android/Apple etc. - -**Logical domains**: Connections may also be made to other logical data domains. For example, there is an [knowledge layer proposal](https://wiki.covesa.global/x/cYI8B) made in the COVESA Data Architecture team that discusses the separation of concerns and interaction between knowledge, information and raw data layers as illustrated below. The Playground here could be used to provide the data/information layer services in its investigation. - -![Knowledge layer proposal](https://wiki.covesa.global/download/attachments/71074417/Knowledge-Layer-v3.png?api=v2?width=50pc "Deployment illustration from the proposal") - Source: [knowledge layer proposal](https://wiki.covesa.global/x/cYI8B) - -### Project success factors - -1. Newcomers to COVESA technology use the playground to accelerate their understanding of how the technology can be used. That could be a looking at a simple instance of how a VSS data server is combined with a VSS data store and queried using VISS. It could also be a more complex instance that combines components to illustrate a longer specific end to end use case, e.g. mobile to vehicle connection. - -2. Internal groups within COVESA naturally use the logical concepts and the playground implementation in combination with other components to develop and disseminate ideas. This especially applies to the Data Architecture and Infrastructure pillar. - -3. Supporting materials such as patterns, diagrams, cookbooks etc are adopted as useful assets within and outside COVESA, which in turn helps socialization. - -## How? - -+ Address two high level implementation needs, keeping in mind a path towards production where possible: - - - Easy to develop: make it easy to build, modify and trial by providing an instance running on a host, e.g. using Docker container(s). - - - Closer to production: the same base code should be deployable to systems closer to production, including on automotive hardware (or its simulation), e.g. Yocto, container orchestration, SOA etc. - -+ A path towards production can be supported by using production components, rather than overly simple substitutes, where it makes sense. For instance a particular scenario may use Kafka in a cloud connection. The point is not to pick a winning product in a particular category, but to recognize that using a production tool can represent a category that is known to scale. Detailed requirements for a specific production project and product selection for it, is rightly left to that project. - -+ A generic code base for the basic building blocks should allow flexible compilation to meet those needs on multiple architectures, e.g. x86, ARM and RISC-V. The target for how it is used being a matter of deployment at a high level. - -+ Follow the OSS mantra of adopt where you can, extend if needed, create where necessary. - -+ Promote flexible reconfiguration of components by favouring loose coupling over tight coupling. diff --git a/docs/docs-gen/content/overview/cdsp-overview.md b/docs/docs-gen/content/overview/cdsp-overview.md deleted file mode 100644 index bb3e6f26..00000000 --- a/docs/docs-gen/content/overview/cdsp-overview.md +++ /dev/null @@ -1,13 +0,0 @@ ---- -title: "Playground overview" -weight: 10 ---- -The Central Data Service Playground (CDSP) serves as a neutral, open playground for data services both within and outside the vehicle in the context of data-centric architectures.
