I am in need of a KeyValue database, with ACID support (I cannot lose any data that was written) that can sustain about 10K reads + 10K writes per second at peak time. Object size varies from 5Kb -100Kb.<p>I don't need indexing for the blob objects as I'll keep a few columns just for index required metadata.
So far I was looking at Postgresql (jsonb and hstore) and Aerospike.<p>What should be some technologies I should consider? Any advice? Thanks!
