We're currently evaluating DSE Cassandra as a data store and are also separately interested in using the Cassandra cache in lieu of a dedicated cache - the data cached would completely fit in-memory for our particular use case.
The 1.0 tuning documentation states the following:
"Some Cassandra production deployments have leveraged Cassandra's caching features to the point where dedicated caching tools such as memcached could be completely replaced."
http://www.datastax.com/docs/1.0/operations/tuning
However the latest documentation does not mention this sort of use for the Cassandra cache. Is anyone still using doing this?
Thanks
