Do we need a cache layer for cassandra?

I am playing/evaluating a realtime streaming application with millions of user activity logs, the design was to use Cassandra as a persistent store and use redis as a cache layer to store recent activities (last 1000). I am looking for a suggestion whether such a cache layer necessary along with cassandra. Is cassandra capable to get best read and write performance? The activities are streamed to front end as pages of 10 or 15 records. Suggestions are expected to use any alternative noSQL solutions as well

It depends a lot on your requirements - Cassandra is reasonably fast for most common purposes, but redis will be faster, so having a caching layer is a reasonable and common approach. It's not strictly necessary, but it's not a bad idea.
