Generally, limit a Cassandra cluster low hundreds of tables, regardless of number of keyspaces.
Beyond low hundreds is certainly an “expert” feature and requires great care. Sure, maybe
you can have 500 or 750 or maybe even 1,000 tables in a cluster, but don’t be surprised
if you start running into memory and performance issues.

There is an undocumented method to reduce the table overhead to support more tables, but...
if you are not expert enough to find it on your own, then you are definitely not expert enough
to be using it.

What's the latest on the maximum number of keyspaces and/or tables that one can have in Cassandra
2.1.x?
