We’ve been using SQL for storing various Spamassassin data for the last few years. It’s allowed us to provide our users with a lot of control and has been a good solution. However, a mixture of a inattention and a failure of some of the maintenance actions has led to a problem with the bayes tables growing to a size that is beyond sensible. We’ve started taking action to remedy the issue, but as we’re presently using MySQL the size of the database files isn’t shrinking 🙁 The effort involved in correcting this is large enough to make me wonder whether it’s an opportunity to migrate to Postgres. Has anyone done this or have any opinions whether it’s a sensible move to make?
