Using Q4M: A Message Queue Storage Engine for MySQL

Average rating: ***..
(3.50, 4 ratings)

Q4M is a message queue that works as a pluggable storage engine of MySQL 5.1.

Originally developed for Pathtraq (one of Japan’s largest web access stats service), the performance and stability of Q4M is highly renowned within the nation, and other organizations have started using it, including Mixi (Japan’s largest SNS provider).

In the presentation, the original developer of Q4M will explain:

  • the design goals and architecure of Q4M
  • how to use Q4M
  • various usage senarios
  • real-world use cases

so that the audiences can understand and start using Q4M to offload, modularize, stabilize web services, and/or to create loosely-coupled services using the message queue.
