Three key things to know about moving MySQL into the cloud.

The question “what problems will I have when migrating to the cloud” gets asked often enough. If by cloud you mean Amazon EC2, then from a technical perspective there isn’t much that changes. The biggest thing that changes is just how you pay your bill. Having said that, there’s still a few potential gotchas: There […]

Improving InnoDB recovery time

Speed of InnoDB recovery is known and quite annoying problem. It was discussed many times, see: http://bugs.mysql.com/bug.php?id=29847 http://dammit.lt/2008/10/26/innodb-crash-recovery/ This is problem when your InnoDB crashes, it may takes long time to start.

Is DRBD the right choice for me?

It seems pretty common to find customers install DRBD for the wrong reasons. There are many pros/cons to compare DRBD to replication, but I’ve managed to cut down my spiel I give to customers to these two points: DRBD’s aim (assuming replication mode C) is to provide 100% consistency, and then as much uptime as […]

Gathering queries from a server with Maatkit and tcpdump

For the last couple of months, we’ve been quietly developing a MySQL protocol parser for Maatkit. It isn’t an implementation of the protocol: it’s an observer of the protocol. This lets us gather queries from servers that don’t have a slow query log enabled, at very high time resolution. With this new functionality, it becomes […]
