> Folks using Astyanax and the like are subject to  https://issues.apache.org/jira/browse/THRIFT-1457
and may run into heap pressure on the Cassandra side for larger read request, as thrift doesn't
reset its internal buffer.  This can lead to larger TFramedTransport instances will be kept
on the heap.
> I've seen at least one situation where this has saved around 1Gb of heap space on average.
