Monitoring integrations

The cookbook describes error reporting integrations using Rollbar and Sentry.Read 4 Oct 2026 · dramatiq.io

Operating system support

The motivation page lists Windows support, while the installation page says the `watch` extra is supported only on UNIX.Read 3 Oct 2026 · dramatiq.io

Prioritization

Dramatiq supports actor priority after messages are consumed from queues, and RabbitMQ supports queued message priority through an option.Read 3 Oct 2026 · dramatiq.io

Python support

Dramatiq officially supports Python 3.10 and later.Read 4 Oct 2026 · dramatiq.io

Dramatiq provides rate limiters, with the cookbook showing a Redis-backed concurrent rate limiter.Read 4 Oct 2026 · dramatiq.io

Rate limiting and metrics extras

Optional installation extras provide a Memcached rate limiter backend and Prometheus metrics middleware.Read 3 Oct 2026 · dramatiq.io

Retries

Failed messages are retried automatically with exponential backoff, and retry behavior can be configured per actor.Read 4 Oct 2026 · dramatiq.io

Scheduling

Actors can schedule messages for later using a delay; the guide says scheduled messages should be a small subset of all messages because the broker is not a database.Read 4 Oct 2026 · dramatiq.io

Security and compliance

The official pages opened identify the project license as LGPL and do not state security certifications or compliance claims.Read 4 Oct 2026 · dramatiq.io

Task execution

Actors can enqueue messages to run asynchronously in worker processes, which can run multiple concurrent workers.Read 4 Oct 2026 · dramatiq.io

Testing

Dramatiq provides a StubBroker for unit tests that do not need a running RabbitMQ or Redis instance.Read 3 Oct 2026 · dramatiq.io

Workflow composition

Built-in groups can run actors in parallel and pipelines can chain actors; result management requires result storage to be enabled.Read 4 Oct 2026 · dramatiq.io
