The ongoing MySQL campaign

... or to find out that you need reliable, trustworthy and fast multi-master clustering to satisfy your load and uptime needs.

Right now, MySQL fails on "reliable" and "trustworthy" for its MM clustering, and PostgreSQL doesn't have it at all. I'm not equipped to evaluate the MM clustering add-ons to Pg like Bucardo, but I'm figuring the approach hasn't been integrated into Pg core for a reason.

Sometimes you really do need things the OSS databases don't yet provide.

That said: frequently, the reasons are lack of understanding, lack of sales materials targeted at middle/upper management, a belief that having another company "standing behind" the product makes it invulnerable to failure, "having someone to sue", or the nice week-long party cruise the salesman promised the TIO if they'll sign on the dotted line.
