Subject Cassandra JVM GC settings
Date Thu, 16 Jun 2011 14:46:53 GMT
Hi Everyone,

I'm seeing Cassandra GC a lot and I would like to tune the Young space and
the Tenured space. Anyone would have recommendations on the NewRatio or
NewSize/MaxNewSize to use for an environment where Cassandra has several
column families and in which we are doing a mixed load of reading and
writing. The JVM has 8G of heap space assigned to it and there are 9 nodes
to this cluster.

Thanks for the comments!
