Unless you are running Redis only with nothing else, fdb and redis do not play in the same space.
Only in terms of transactions across multiple data centers. In every other way vertically scaler sql performs better, especially for your dollar.
But of course, hence why i referenced multidc transactions.
Not to my understanding. Can you elaborate?
I think they have different use cases: fdb when you want transactions, cassandra when you want throughput.
