implement master-slave DB for beta labs
Closed, ResolvedPublic

Description

The beta cluster is intended to be "close" to production for testing purposes, but it does not use a master-slave DB configuration. This means that some cache and database bugs aren't caught in testing on beta labs, e.g. bug 59884.

It would be useful if beta labs had a similar master-slave DB setup, especially if we introduced significant lag time in slave updates. Easier said than done :-)

setting the lag is fairly trivial, percona makes a tool for it called pt-slave-delay.
