What probably matters to youSection of the release
Server-pushed work_available hints over SSE sit behind CCR_SHR_SSE_HINTS, off by default, and nothing else in the build enables it.
What
Set CCR_SHR_SSE_HINTS and the runner holds an event-stream connection to the server and wakes its poll loop as soon as a work_available event arrives, instead of waiting out the full poll interval. It defaults to off, and nothing else in the build turns it on.
Details
Wakes are jittered by up to 200ms to spread out a fleet reacting to the same event, and the wake source is reported back to the server.
The stream times out after 45 seconds without a read and reconnects with exponential backoff capped at 30 seconds.
Wakes are suppressed while the runner is already at capacity.
