What is Dragonfly?

Dragonfly opens a 2.1 line with metrics that explain why replicas drop.

Dragonfly tagged v2.1.0 on November 4, exporting snapshot counters, a save-in-progress gauge and replica disconnects labeled closed, error or timeout. Before, a replica dropped for stalling was indistinguishable from one whose connection simply closed. The 1.40 and 2.0 lines keep getting small cluster-mode fixes, including faster GetSlotInfo and slot migration that no longer drops writes.

What is Hatchet?

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

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.

Dragonfly vs Hatchet: editorial side-by-side

D
Dragonfly
INFRA · APIS
5.0

Dragonfly opens a 2.1 line with metrics that explain why replicas drop.

◆ Current state

Dragonfly tagged v2.1.0 on November 4, exporting snapshot counters, a save-in-progress gauge and replica disconnects labeled closed, error or timeout. Before, a replica dropped for stalling was indistinguishable from one whose connection simply closed. The 1.40 and 2.0 lines keep getting small cluster-mode fixes, including faster GetSlotInfo and slot migration that no longer drops writes.

◆ Where it's heading

Dragonfly is maturing for production operations: the 2.0 line fixed cluster correctness, and 2.1 starts by making replication and persistence observable from Prometheus. The project says it prefers small incremental features, so 2.1 will likely grow the same way.

◆ Prediction

More metrics and cluster-mode fixes on 2.1, with 1.40 and 2.0 still getting backports for a while.

6.3

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

◆ 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.
