OllamaMQ v0.3.0 represents a significant architectural and operational leap forward, particularly in performance, security, and observability. The core changes include: 1. Performance Boost: Refactoring to a lock-free ring buffer reduces latency by 30% (from 2.5ms to 1.7ms) and doubles throughput under mixed loads. The new batch-publish API supports up to 10k messages per RPC call, ideal for high-frequency telemetry pipelines. 2. Pluggable Transport Layer (PTL): Flexibility to choose between T

OllamaMQ v0.3.0 represents a significant architectural and operational leap forward, particularly in performance, security, and observability. The core changes include:

·
Performance Boost: Refactoring to a lock-free ring buffer reduces latency by 30% (from 2.5ms to 1.7ms) and doubles throughput under mixed loads. The new batch-publish API supports up to 10k messages per RPC call, ideal for high-frequency telemetry pipelines.
·
Pluggable Transport Layer (PTL): Flexibility to choose between TCP (default), Unix-sockets (lowest latency), TLS (secure), or QUIC (lossy networks) without recompilation. Example config: yaml transport: type: quic listen: ":4433" tls: cert: /path/to/cert.pem key: /path/to/key.pem
·
Zero-Trust Security: Built-in mTLS enforces mutual authentication, while JSON-Path ACLs allow granular topic access control per client certificate fingerprint.
·
Observability: Native OpenTelemetry integration emits spans and metrics (e.g., ollamamq.topic.msg_rate), combinable with the new React-based dashboard for real-time monitoring of topic lag and consumer health.
·
Message Enhancements: Protocol-level headers (CBOR-encoded) and TTL enable metadata-driven routing and automatic expiration of stale messages.
·
Durability Choices: Memory-only (low-latency), RocksDB-backed (persistent), or hybrid modes, with CLI tools for incremental snapshots (ollamamq snap create|load).

Upgrading is straightforward with backward-compatible SDKs (Go, Python, Rust, Node.js) and a v0.2.x shim. For new deployments, prioritize this version if you need production-grade messaging with security and visibility baked in.

Quick Start:

·Run ollamamq server --config ollamamq.yaml
·Install SDK (e.g., pip install ollamamq==0.3.0)
·Monitor via http://localhost:8080/ui or OTEL endpoints.
