Apache Cassandra 0.6.6 Gets More Default JVM Options

Apache Cassandra version 0.6.6 has been announced.

This release adds CMSInitiatingOccupancyFraction=75 and UseCMSInitiatingOccupancyOnly to default JVM options. These options tell the JVM to always start a collection when the heap is 75% full. IndexInterval is now configurable, and cache information has been added to GCInspector logs. If JNA if present, Cassandra will now use it to take snapshots – if JNA is not available, Cassandra will fall back to the pre-existing method.
