Subject Re: need help with Cassandra 1.2 Full GCing -- output of jmap histogram
Date Sun, 09 Mar 2014 20:24:54 GMT
You have millions of org.apache.cassandra.db.DeletedColumn instances on the
snapshot.

This means you have lots of column tombstones, and I guess, which are read
into memory by slice query.
