"Redis is an open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker"

Lets draw the line somewhere the other side of applications that advertise themselves as having that function?

The number of people that think that Redis is a KV store and nothing else is too damn high.

Redis is not a database. it doesn’t have proper transaction support.

it’s basically a cache with a fancy API so you can incrementally update data structure instead of having to constantly write the whole thing you are trying to cache.

Sure it is! Redis is even fully ACID if you use the right persistence settings complete with transactions support and a WAL. You can even set up locking to abort/rollback transactions. In DB parlance Redis’ isolation level is strict serializability which is stronger than Postgres.

If you mean “it doesn’t have every feature of Postgres” and behaves a little differently then sure but it absolutely is a database.
