How Percona Toolkit divides tables into chunks
May 06 2012
The tools we’ve redesigned in Percona Toolkit recently have moved away from a legacy technique for operating on small numbers of rows at a time, towards a more reliable and predictable method.

I got a really intriguing email today. As you might imagine, I get a lot of email offering to advertise, or trade links, or guest post, etc etc. But this is the most compelling one I’ve ever gotten: I came across your blog http://www.xaprb.com/blog/2009/03/13/50-things-to-know-before-migrating-oracle-t o-mysql/ a few weeks ago as while… read moreFree webinar: non-blocking MySQL schema changes

What are your pet peeves about the tools? I have a lot. For example, pt-table-sync doesn’t let me do things I want it to do sometimes (and I know it could be made to do them). Another example: pt-query-digest’s tcpdump parser doesn’t pay attention to TCP sequence numbers, so sometimes… read moreWebcast: Diagnosing Intermittent MySQL Problems
