OSCON, Portland, and PDXPUG
After spending an awesome week in San Francisco, CA I’m lucky enough to be spending another week in the USA, in Portand, OR. The main excuse for showing up here has been OSCON where I presented a talk about the fotolog migration from MySQL to PostgreSQL.
Fotolog is a photo sharing website having more than 32 millions of users sharing more than a billion of photos, which made for a very interesting migration use case. In particular switching from a hand-made MySQL sharding cluster of 37 databases to a fully integrated PLProxy setup on 16 servers hosting each 16 shards, in less than 6 months including complete code rewrite, made things… interesting.
While in Portland I also had the pleasure to present a talk at the PGXPUG User Group Meeting, hosted by MyEmma who provided a very nice place, beers and pizzas. Meeting with local users is always a great time, and I’ve presenting the PostgreSQL as a developer talk that I also did for the Dublin User Group, which you can see online at my Dublin User Group conference report page.
Of course the technical answer is all of it, as demonstrated by apache mod_libpq, wherein URLs are simply transformed into stored procedure calls. Which in PostgreSQL you can implement in basically any programming language you want, like PL/Python or PL/Perl to give but only two examples.
