Hatchet chases DAG crash loops through three engine patches in a day.

durable-executionreliabilitysdkssandboxestesting
◆Current state
Hatchet added sandboxes, Labs switches and cloud MFA in early November. The week since has been engine reliability: v0.120.3 batches DAG step triggers, v0.120.4 fixes stranded match rows and prunes database partitions before locking, and v0.120.5 removes another cause of DAG crash loops. Python SDK 1.46.0 makes it easier to unit-test tasks and passes failures to cleanup dependencies.
◆Where it's heading
After a burst of features, Hatchet is tuning the engine under load: fewer locks, batched triggers and crash-loop fixes. The SDKs are getting testing and correctness work to match.
◆Prediction
Expect more v0.120.x patches on DAG handling, then a sandbox package out of release candidate.

    Python SDK 1.46.0

    Mock runs can now simulate task failures, trigger data and run ids, so on-failure and wait-for tasks can be unit-tested. Dependency fixes also let cleanup code see the task's exception, which suits the week's focus on correctness.

    An engine fix for match rows left behind, part of the same day's reliability patches.

    v0.120.4 alpha prunes partitions before locking

    A database change so lookups lock fewer task partitions, with a cache for id lookups. Internal performance work with no setting to change.

    Hatchet sandbox package 0.1.5 release candidate

    A sandbox package release candidate with no notes. It shows sandboxes, added in v0.117, are still pre-release.

    Hatchet v0.120.3 batches DAG step triggers

    The operator now triggers DAG steps in batches. Engine efficiency work that follows v0.120's move of DAG operators to every dispatcher.
