The Spread Toolkit

(via)
Spread is an open source toolkit that provides a high performance messaging service that is resilient to faults across local and wide area networks. Spread functions as a unified message bus for distributed applications, and provides highly tuned application-level multicast, group communication, and point to point support. Spread services range from reliable messaging to fully ordered messages with delivery guarantees. Spread can be used in many distributed applications that require high reliability, high performance, and robust communication among various subsets of members. The toolkit is designed to encapsulate the challenging aspects of asynchronous networks and enable the construction of reliable and scalable distributed applications. Spread consists of a library that user applications are linked with, a binary daemon which runs on each computer that is part of the processor group, and various utility and demonstration programs.

Design details of Audiogalaxy.com’s high performance MySQL search engine | Spiteful.com

(via)
As I mentioned before, search was one of most interesting problems I worked on at Audiogalaxy. It was one of the core functions of the site, and somewhere between 50 to 70 million searches were performed every day. At peak times, the search engine needed to handle 1500-2000 searches every second against a MySQL database with about 200 million rows. It was frequently hard to design for more than 10 or 100x our current traffic (and our growth was so dramatic that there wasn’t really ever time to spend more than a few weeks on the problem), so it wasn’t until the 4th major iteration on the cluster design that I really considered the scale problems to be solved.
