Thanks to Jeremy Cole for finding out the truth.

]]> Comment on Sphinx search performance optimization: attribute-based filters by Aurimas Mikalauskashttp://www.mysqlperformanceblog.com/2013/01/15/sphinx-search-performance-optimization-attribute-based-filtering/#comment-1838921 Aurimas Mikalauskas Thu, 13 Jun 2013 10:17:15 +0000 http://www.mysqlperformanceblog.com/?p=12300#comment-1838921 Fabian, -

please note that, as stated in the article, this technique only works well for highly selective attributes. If attributes only have few distinct values (e.g status, gender, group_id with only 10 groups per 10M records), then you don’t want to use this. Please see “Highly selective columns only” section for examples where it doesn’t work well for us too.

I think the performance schema will be a great addition to MySQL once it’s more established. Just starting with MySQL after retiring from handling oracle databases – now volunteering :) Thanks for sharing.
