Database operations gets interesting when it involves several thousand databases, a high-profile site and you have a small core team of DBAs. Among other things, we will give a high-level overview of Facebook database architecture, Backup (and recovery) strategy and the mysql upgrade process. We will also go over an internally developed distributed handler to run several concurrent jobs locally on remote machines used to handle the daily needs for sharding and de-fragmentation. We will also delve into the challenge of dealing with a constantly updated applications, getting diagnostic information on the fly and the mantra of “automating everything”.
