"description": "[EuroPython 2023 \u2014 Terrace 2A on 2023-07-21]\nhttps://ep2023.europython.eu/session/fish-and-chips-and-apache-kafka\n\nApache Kafka\u00ae is the de facto standard in the data streaming world for sending messages from multiple producers to multiple consumers, in a fast, reliable and scalable manner. Come and learn the basic concepts and how to use it, by modelling a traditional British fish and chips shop!\n_________________________\n[ *CORRECTIONS FROM THE SPEAKER* ]: \nWhen talking about two of the slides in the video, I say *\"topic\"* when I should have said *\"partition\".* Below is the text as it should be - the highlighted words are what I should have said.\n\ud83d\udd37 At 7:14 - slide *Multiple partitions, consumer groups:* \n\ud83d\udd39Sometimes that's not what you want. Sometimes you want your consumers to share the reading, so here we've got two *partitions,* one with 1, 2, 3 and one with b, c, d in it.\n\ud83d\udd39The producers [...] can choose which partition by hand, say I want *partition* one, two, three, or you can say here is a key, choose by the key which *partition* to go to.\n\ud83d\udd39The consumers at the top right are in the same consumer group, they said \"we want to share consuming the *topic\".* \n\ud83d\udd39Each consumer will get one or more *partitions,* but they won't both see the same *partitions.* So one of them is seeing 1, 2, 3 and the other is seeing b, c, d. The bottom consumer is not in a consumer group, it's entirely independent, and like the previous consumers it's just getting all the messages in order.\n\n\ud83d\udd37 At 14:43 - slide *Three tills:* \n\ud83d\udd39So now we're going to add three producers and we'll add three *partitions,* because then we can say each till will send to a separate *partition.* The food preparer is still reading from all of them so it will get things interleaved nicely.\n_________________________\nThis work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License http://creativecommons.org/licenses/by-nc-sa/4.0/",
