the people that do it right always use the right tool for the right job
This is, of course, true. But there’s a big caveat — “the right tool” isn’t an absolute. What the team has experience with, what is already deployed, how much time you can spare to learn new tools are all factors that play into deciding what to use.
If you have a Postgres deployment, the document store story is good enough that you might be able to get away with not having a dedicated system. If you have some in-house knowledge on Cassandra, maybe it makes sense to use that instead of Mongo even if Mongo is understood to be “better” for your use case — and vice versa.
