The newest release of Maatkit contains mk-audit bug fixes, lots of new features for mk-table-checksum so you can check replication more frequently (see my earlier post about this), and more bug fixes for other tools.

Here’s the changelog:

Changelog for mk-audit:

There’s a Facebook event for OpenSQL Camp. If you RSVP to it, your friends will find out, and that will help spread the word.

I’ve been working with a client recently who has SELinux on his servers.  It has been quite a struggle sometimes.

My colleages tell me that SELinux has a pretty noticeable performance impact.  I am not sure if we have benchmarks to support this; at any rate, the client said it’s OK, we’ll take the performance hit.

I just wrote about how Maatkit has gotten some new features for helping people make sure their slaves have an exact copy of the master’s data. This work was largely sponsored by one of Percona’s customers, whose name I have permission to mention: Vantage Media.

I have recently added some features to Maatkit’s mk-table-checksum tool that can make it easy to checksum the relevant parts of your data more frequently (i.e. continually, but not continuously). This in turn makes it possible for you to find out much sooner if a slave becomes different from its master, and then you [...]
