Is it possible to flush memtable in one virtual center?

[Benyi Wang]

We have one ring and two virtual data centers in our Cassandra cluster? one
is for Real-Time and the other is for analytics. My questions are:

   1. Are there memtables in Analytics Data Center? To my understanding, it
   is true.
   2. Is it possible to flush memtables if exist in Analytics Data Center
   only?

I'm using Cassandra 1.0.7 for this cluster.

Thanks.
