Reading the FAQ http://wiki.apache.org/cassandra/FAQ <http://wiki.apache.org/cassandra/FAQ> "SSTables that are obsoleted by a compaction are deleted asynchronously when the JVM performs a GC. You can force a GC from jconsole if necessary"
How can i force the GC with a simple java commandline? Is this a bad idea? Since i have lots of inserts and deletes I could save 2X or 3X of my disk requirements, about 40GB to 80GB which is useful on hosting where disk is expensive. Thanks, Karl
