Changelog

Safety And Performance

• #3248

  Fix a bug where grid.cancel was erroneously being invoked during commit_stage=checkpoint_durable.

• #3245

  Remove peer type from MessageBuffer, maintaining it only at MessageBus level.

  This solves a bug introduced by #3206,
  due to divergent peer state between MessageBus and MessageBuffer.

• #3226,
  #3230,
  #3223,
  #3222

  Low-level LSM performance improvements. The k-way merge iterator now uses a tournament tree
  instead of a heap, we skip sorting of the mutable table if it's not needed, and we skip binary
  search if possible by min/max key ranges.

• #3237

  Use a different PRNG seed for Replica each time, rather than a fixed seed of the replica ID. This
  PRNG controls things like exponential backoff jitter and the order of the blocks on which the grid
  scrubber runs.

Features

• #3253

  Introduce --requests-per-second-limit to throttle CDC requests to TigerBeetle.

  Usage for this option is orthogonal to --idle-interval-ms and --event-count-max, allowing
  fine-tuning for low latency without overflowing the AMQP target queue.

• #3206

  In order to avoid bimodality if a replica is down (eg, a client sends a request, doesn't hear
  anything, eventually times out and tries a different replica) clients now proactively send their
  requests to the primary and a randomly selected replica.

  Backups can also send replies directly to clients, meaning that a client could be completely
  partitioned from the primary, but still remain available.

Internals

• #3251

  Mark grid cache blocks as MADV_DONTDUMP, making core dump size tractable even with large caches.

• #3227,
  #3231,
  #3242

  Preparation for the Zig 0.15.1 upgrade.

• #3236,
  #3229,
  #3198

  A host of multiversion improvements! Multiversioning is now a proper interface, rather than being
  scattered about. Additionally, Windows support is now significantly more robust, and will be
  integration tested like the other platforms in the next release.

  Retain table repair progress across checkpoint boundaries,

• #3210,

• #3199,
