Description

As part of CASSANDRA-13853, there was a method introduced into StorageServiceMBean via which an operator can retrieve information about a particular keyspace. This method is very handy not only in the context of 13853 and I am lacking that method in 3.11 as it was not ported there. I would like to have that method in 3.11 too for observability purposes as well as for the feature parity with 4.0.
