We now store over 250 million entries and a bunch of other data, from comments and "likes" to friend lists. As our database has grown, we have tried to iteratively deal with the scaling issues that come with rapid growth. We did the typical things, like using read slaves and

Quick comparison of MyISAM, Infobright, and MonetDB
Recently I was doing a little work for a client who has MyISAM tables with many columns (the same one Peter wrote about recently). The clientâ€™s performance is suffering in part because of the number of columns, which is over 200. The queries are generally pretty simple (sums of columns), but theyâ€™re ad-hoc (can access any columns) and it seems tailor-made for a column-oriented database. I decided

Kazuho@Cybozu Labs: Mycached: memcached protocol support for MySQL
It is a well-known fact that the bottlenecks of MySQL does not exist in its storage engines, but rather in the core, for example, its parser and execution planner.Â Last weekend I started to wonder how fast MySQL could be if those bottlenecks were skipped.Â Not being able to stop my curiousity, I startedÂ adding memcached proctol support to MySQL as a UDF.Â And that is Mycached.
