Changelog

As of TigerBeetle 0.17.4, the minimum required Linux kernel version is 5.11.

Safety And Performance

• #3619

Refactor and simplify the Linux IO event loop, by directly embedding a timeout when calling io_uring_enter, making next_tick a top level function (instead of executing all callbacks back to back) and reentering the kernel after each callback.

Combined, these changes give a ~8% improvement on the standard benchmark, improve tail latencies in certain edge cases, as well as prevent tick starvation under heavy load or slow disks.

• #3701

Fix a bug in reformat caused by invoking IO.run from within IO.run_for_ns.

• #3680

Track the object caches as metrics, to help with sizing (eg, --cache-accounts).

• #3693

Fix file permissions to no longer ask for world readable/writable files when creating them. Normally, this does get prevented by the default umask.

Internals

• #3698

Add warnings when the event loop is slow.

• #3694, #3684

Cache the Zig download for test workflows, add the flake count to Devhub and miscellaneous CI fixes.
