TinyMQ - Official Release Notes

This is the first official release of TinyMQ. It evolves the initial prototype into a robust, lightweight, and production-ready message broker.

Added

Disk Persistence (WAL): Implemented a write-ahead log using append-only .log files per topic to ensure zero message loss.
Auto-Compaction: Automatic purge algorithm on server boot to clean up acknowledged (ACK) records and free disk space.
Reactive Long Polling: Efficient message consumption by suspending goroutines via Go channels with timeout support.
Wildcard Routing: Support for consuming topics using patterns (e.g., events.*) with a pre-compiled regex caching system.
Official Go SDK: Native client at client/client.go with robust subscription mechanisms, exponential backoff (1s up to 32s), and re-queuing on failures.
Integrated Web Dashboard: Lightweight UI at /dashboard for monitoring topics, pending messages, and RAM usage.
CI/CD Pipeline: GitHub Actions workflow (release.yaml) for multi-platform binaries and Docker image publishing to GHCR.

Lock-Free Routing: Minimize global lock contention by releasing the broker mutex before disk I/O.
Graceful Shutdown: Intercept SIGTERM/SIGINT to flush and close files cleanly.
Memory Leak Prevention: Explicit nil assignments before reslicing and handling of r.Context().Done() to free blocked goroutines.
File Descriptor Caching: Reuse open *os.File handles to reduce OS-level open/close overhead.

Multi-stage Docker image based on Alpine, final image under ~20MB.
Production orchestration via docker-compose.yml, mounting a persistent ./data directory.

Docker Image: docker pull ghcr.io/x-name15/tinymq:1.0.0
