Release Checklist

This checklist must be completed before publishing a release of any kind.

Over time, anything in this list that can be turned into an automated test should be, but there are still some big blind spots.

API stability

  • rust-flavored semver respected

Performance

  • micro-benchmark regressions should not happen unless newly discovered correctness criteria demands them
  • mixed point operation latency distribution should narrow over time
  • sequential operation average throughput should increase over time
  • workloads should pass TSAN and ASAN on macOS. Linux should additionally pass LSAN & MSAN.
  • workload write and space amplification thresholds should see no regressions

Concurrency Audit

  • any new Guard objects are dropped inside the rayon threadpool
  • no new EBR Collectors, as they destroy causality. These will be optimized in-bulk in the future.
  • no code assumes a recently read page pointer will remain unchanged (transactions may change this if reads are inline)
  • no calls to rand::thread_rng from a droppable function (anything in the SegmentAccountant)

Burn-In

  • fuzz tests should run at least 24 hours each with zero crashes
  • sequential and point workloads run at least 24 hours in constrained docker container without OOM / out of disk
