Kazuho at Work: Q4M - 0.6 release and benchmarks
Today I have uploaded Q4M (a Queue for MySQL) 0.6, which is basically a performance-improvement from previous releases. Instead of using pread's and a small user-level cache, Q4M (in default configuration) now uses mmap for reads with a reader/writer lock to improve concurrency. I also noticed that it would be possible to consume a queued row in one SQL statement. SELECT * FROM queue_table WHERE q

This document discusses the history and capabilities of Q4M, an open-source message queue plugin for MySQL. It was created in 2008 by Cybozu to provide a robust, fast messaging system accessible via SQL. Major Japanese companies like DeNA, Livedoor and Mixi use Q4M for asynchronous communication between services. The document also covers related projects like Mycached, a memcached-like plugin, and
