Roadmap

Fibril is still early. The near-term roadmap is about making the existing semantics complete and user-facing before adding larger distributed-system features.

Near term

• Wire public delayed publish through the Rust client.
• Wire msg.retry_after(..) through client, protocol, broker, and Stroma.
• Expose dead-letter policy configuration through the broker.
• Add broker-level tests for DLQ and delayed retry public paths.
• Make server configuration production-friendly instead of hard-coded development defaults.
• Improve TCP protocol ergonomics and error behavior.

Medium term

• Package runnable broker images or binaries.
• Add deployment guidance for the broker itself.
• Improve admin interface observability.
• Produce repeatable benchmark reports.
• Tighten memory behavior under large queue depth and high inflight load.

Longer term

• Replication design and implementation.
• Clustering and partition ownership.
• More complete client ecosystem.

Not initially planned

Transactions are not an initial goal. Fibril is aiming for clear durable messaging semantics, not a clone of every broker feature.
