MoonMQ v0.1.0

First tagged release of MoonMQ, a message broker written in Lua 5.4.

This is a source release: there are no prebuilt binaries. See the README for how to install the dependencies and run the broker.

Highlights

Messaging

• Topics and partitions on an append-only commit log, with compaction and segment rolls
• Grow a topic's partition count with CREATE_PARTITIONS
• Batching, transactions and a dead-letter queue
• Consumer groups, seek by timestamp, LIST_OFFSETS, and topic and consumer-group admin

Clustering

• Replication with failover and in-sync replicas
• Raft consensus for controller and cluster metadata

Security

• Multiple users with ACLs, quotas and authenticated metrics
• SCRAM-SHA-256 with channel binding (tls-server-end-point and tls-exporter)
• TLS, including client-certificate login and certificate reload on SIGHUP

Durability fixes

• atomic_write fsyncs, and every temp-file save goes through it
• Push offsets are committed only after frames reach the socket
• Sync results are checked on transaction markers and replica appends
• Commit-log offsets stay stable through compaction and rolls
