Next Deadline: 1.23 Cycle Begins, August 23
Roughly one week after the new release cycle begins, the Production Readiness Review team would like to have all of your requests to review KEPs. They realize this is an early deadline, and call for shadows to learn PRR so that they can expand bandwidth for KEP review.
Patch versions 1.19.14, 1.20.10, and 1.21.4 came out last week. Changes consist primarily of updating the Go version, with a few miscellaneous bug fixes.
The Events subsystem has many protections to keep the flood of data from overwhelming kube-apiserver. Two major ones are implemented in the event recorder system in client-go, deduplication and rate limiting. While duplication checks the whole event struct, the rate limiting system has, so far, only looked source and involved object. This can now be customized for situations where rate limits should also take into account other data such as the event Reason field (different Reasons could be bucketed separately). When constructing the recorder, you can now specify a SpamKeyFunc in the correlator options to provide your own stringification, including whichever data is important for your use case.
A number of utility functions for managing preemption in scheduler plugins have been shuffled into their own package to make it easier for out-of-tree consumers. If you were previously importing helpers from scheduler/framework/plugins/defaultpreemption, check out the new and improved versions!
