The Paranoid Pirate pattern in ZeroMQ isn't about ensuring your messages are delivered to everyone reliably; it's about ensuring you don't get cheated b.
ZeroMQ Performance Benchmarks: Latency and Throughput
ZeroMQ's real magic isn't just in its message queuing; it's in how it makes distributed systems feel like local ones, often with performance that rivals.
ZeroMQ Poller and Reactor: Event Loop Patterns
The ZeroMQ poller and reactor are not about waiting for messages; they're about actively managing multiple connections and their readiness to send or re.
ZeroMQ Proxy: Forwarder, Streamer, and Queue Devices
The ZeroMQ proxy devices aren't just simple bridges; they're stateful intermediaries that actively manage message flow, often holding messages in memory.
