How else can you spend thousands of dollars an year to get an horrible programmer experience at the expense of performance and data safety?

Plenty of people are stuck with Oracle, but starting with it nowadays is something else.

Oracle provides multimaster replication.

Yep. And either the Oracle support is completely incompetent at my workplace region, or the more servers you add to your multimaster replication, the less is your total throughput. Starting at the 1 to 2 change.

I still believe it's a case of the Oracle people being incompetent, and the system technically being able to scale at a rate somewhat larger than 1. But if a potential gain can be acquired for a few million grand, but nobody has the technical capacity to actually acquire it, is the potential actually there?
