Subject Re: Cassandra 1.1.1 on Java 7
Date Tue, 11 Sep 2012 21:05:34 GMT
So, my experiment didn't quite work out.

I was hoping to use G1 collector to minimize pauses -- pauses didn't 
really go away, but what's worse is I think the memtable memory 
calculations are driven by CMS, so my memtables would fill up and cause 
Cass to run out of heap :(
