My point being is that there is no free solution. There simply isn't.
I don't know why you insist on keeping all your data in RAM, but the
mysql cluster requires that ALL data MUST fit in RAM all the time.
PostgreSQL has replication, but not partitioning (which is what you want).
So, your only option is Oracle or another very expensive commercial
database.
