Native: use IPC instead of flushing to disk where possible #1834
Description
Proposal: use IPC instead of flushing to disk to speed up scope changes, such as setting tags. For example, send messages over a named pipe on Windows.
As a rough comparison, with Crashpad (Windows Defender and external crash reports disabled):
- flush scope to disk (set tag): ~0.5ms
- send IPC message (add attachment): ~0.1ms
Based on that, we could estimate that switching the native backend from disk flushes to IPC messages could result in a ~5x speedup when setting tags on Windows.

Even though
sentry__scope_apply_to_eventis a relatively small part of the whole scope flush process, it's also worth noting that #1794 optimizes that part quite a bit:jpnurmi commentedon Sep 16, 2026
