What is Dragonfly?

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

What is RabbitMQ?

RabbitMQ 4.4 moves to Erlang 28 and tightens OpenID Connect checks, with 4.3 still patched.

RabbitMQ shipped 4.4.0 on October 28 with full Erlang 28 support and stricter OpenID Connect discovery validation that can break setups with non-compliant identity providers. The 4.3 line keeps receiving maintenance releases: 4.3.6 in September fixed exchange deletion leaving behind bindings that pointed to it, quorum queue membership reconciliation adding too many replicas, and double-counted message store references in classic queue recovery; 4.3.7 followed in October.

Dragonfly vs RabbitMQ: editorial side-by-side

D
Dragonfly
INFRA · APIS
5.0

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

◆ Current state

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

◆ Where it's heading

The 2.0 line is maturing through cluster and migration work, while 1.40 gets targeted performance backports. Release cadence has slowed from paired weekly builds to occasional single fixes.

◆ Prediction

Expect further 2.0.x builds focused on cluster mode and slot migration; whether scope-based memory tracking gets switched on is still unclear.

R
RabbitMQ
INFRA · APIS
5.0

RabbitMQ 4.4 moves to Erlang 28 and tightens OpenID Connect checks, with 4.3 still patched.

◆ Current state

RabbitMQ shipped 4.4.0 on October 28 with full Erlang 28 support and stricter OpenID Connect discovery validation that can break setups with non-compliant identity providers. The 4.3 line keeps receiving maintenance releases: 4.3.6 in September fixed exchange deletion leaving behind bindings that pointed to it, quorum queue membership reconciliation adding too many replicas, and double-counted message store references in classic queue recovery; 4.3.7 followed in October.

◆ Where it's heading

Feature work has moved to 4.4 while 4.3 absorbs correctness fixes, many in quorum queues and cleanup paths. The stricter OIDC validation in 4.4 continues the security tightening seen in 4.3.5's encrypted management login tokens.

◆ Prediction

Expect 4.4.x patches, likely including fixes for identity providers caught by the stricter OIDC checks, alongside further 4.3.x maintenance.
