Scaling memcached at Facebook. Fascinating techie details on how Facebook forked memcache to use UDP and increase performance from 50,000 requests a second to 200,000. Now running on 800 servers with 28 TB of memory, and their code is on GitHub. (They may scale like crazy, but they can’t put their blog entry title in the title element?) # 13th December 2008, 10:08 am

Spock Proxy. A MySQL Proxy fork (no Lua) that concentrates solely on sharding, by parsing incoming SQL statements and redirecting them across multiple databases. There are some limitations on the SQL that can be handled (no nested queries, joins across a maximum of two tables) but generally it looks pretty impressive. # 11th December 2008, 9:49 am
