My first blog entry way back in Sep 2005 was about RubyForge and the PostgreSQL database. At that time RubyForge had three million records in the database, which seemed like a bunch. Well, times have changed, and that database now holds sixteen million records! Of course, I know, that's small potatoes, EBay has that many records in their glove compartment, etc, but still.

Fortunately the top couple of tables are mostly just logs. For example, the gem_downloads table has a little over six million records and is getting 15-20K more records each day, but it's not indexed and is only queried from cronjobs. The activity_log table is the same sort of thing - it has a little under three million records, and receives about 500K inserts per day, but that's a rolling log and thus records older than a week just get deleted. Come to think of it, I should probably exclude those tables from autovacuum.

But anyhow, PostgreSQL is holding up fine under the load, and it looks like PostgreSQL 8.2 will bring in a lot of performance enhancements to boot. Good times!
