[jira] [Created] (CASSANDRA-8887) Direct (de)compression of internode communication

Matt Stump created CASSANDRA-8887:
-------------------------------------

             Summary: Direct (de)compression of internode communication
                 Key: CASSANDRA-8887
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8887
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Matt Stump


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.
