MySQL does support Master/Slave replication. In fact a master (for writes) can have multiple slaves (read only). That's a good idea - and it'll buy us time while we explore how to scale up the DB that handles all the writes. Going forward, a master/slave setup solves only half of the problem.
I'd like to learn how to introduce some redundancy into our data setup, so if one machine crashes, others can keep the data flowing. AFAIK the only open-source database that offers true redundancy for reliability is Cassandra. Am I wrong?
