> Internode compression is on by default. Currently we allocate one set of buffers for
the raw data, and then compress which results in another set of buffers. This greatly increases
the GC load. We can decrease the GC load by doing direct compression/decompression of the
communication buffers. This is the same work as done in CASSANDRA-8464 but applied to internode
communication.
