RabbitMQ vs Thanos
A side-by-side editorial comparison of RabbitMQ and Thanos — release velocity, themes, recent moves, and the top alternatives to consider.
RabbitMQ vs Thanos: at a glance
What is RabbitMQ?
Two parallel trains, and the 'maintenance' label is now hiding real feature work
RabbitMQ is maintaining 4.2.x and 4.3.x side by side, cutting matching patches into both on the same day, and both trains raised their floor to Erlang/OTP 27. Most of the window is correctness work in the Raft-backed subsystems — quorum queues losing metrics after a restart, leaders committing log entries too optimistically, classic queue index paths accumulating slashes, topic bindings with empty routing keys matching everything. The newest 4.3.5, however, is labelled a maintenance release while carrying encrypted management-UI login tokens, a new authentication logging category, ETag support on the definitions endpoint, and a self-deleting Shovel TTL.
What is Thanos?
Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.
Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.

Two parallel trains, and the 'maintenance' label is now hiding real feature work
◆ Current state
RabbitMQ is maintaining 4.2.x and 4.3.x side by side, cutting matching patches into both on the same day, and both trains raised their floor to Erlang/OTP 27. Most of the window is correctness work in the Raft-backed subsystems — quorum queues losing metrics after a restart, leaders committing log entries too optimistically, classic queue index paths accumulating slashes, topic bindings with empty routing keys matching everything. The newest 4.3.5, however, is labelled a maintenance release while carrying encrypted management-UI login tokens, a new authentication logging category, ETag support on the definitions endpoint, and a self-deleting Shovel TTL.
◆ Where it's heading
The bug pattern remains the tell: nearly every fix is in quorum queues, Khepri or Raft, which is where RabbitMQ moved its metadata and durability story after 4.3.0 removed Mnesia and partition-handling strategies outright. Layered on top is a steady tightening of the operational perimeter — protocol parsers rejecting malformed input strictly across AMQP 1.0, MQTT 5.0 and STOMP, pre-authentication frame limits on stream connections, HTTP API endpoints validating node membership, and headers that stop disclosing supported methods. Feature work is arriving inside patch releases rather than waiting for a minor.
◆ Prediction
Expect the 4.2.x train to slow toward end-of-life while 4.3.x patches keep absorbing both Khepri edge cases and security-surface work. The encrypted login token, currently opt-in behind a shared cluster secret, is the kind of setting that gets promoted to a default once rolling-upgrade friction is behind it.
Thanos
0.0INFRA · APIS
Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.
◆ Current state
Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.
◆ Where it's heading
The centre of gravity is multi-tenant operation. Per-endpoint configuration and tenant lifecycle handling are what an operator needs to run one Thanos install for many teams rather than one per team, and the Query fanout view is the observability that makes such a topology debuggable. The parallel fixes to multi-tier query setups — preserving external label matchers across Query A → Query B → Sidecar chains — point at the same reality: deployments are getting deeper, not just wider.
◆ Prediction
A 0.42.0 stable should follow once the *os.Root regressions settle. The RC notes are cumulative and the feed is quiet since June, so treat cadence here as release-train artefact rather than a slowdown in the project.
