Whats your opinion on postgres vs nosql like cassandra and aerospike, fundamentally is there any reason that postgres can't scale as well as nosql? If I store key value in postgres and add read replica to scale read and partition to scale write will I not be able to keep up with other nosql solutions? If so what are the reasons?

I would say that by the time you (potentially) have those kinds of problems, you'll most likely have the resources to deal with them.

It's sort of a nice class of problems to have, and a lousy heuristic for choosing solutions before you know what exactly you're dealing with.
