URL: https://issues.apache.org/jira/browse/CASSANDRA-15556
Project: Cassandra
Issue Type: Bug
Components: Messaging/Client
Reporter: David Capwell
Assignee: David Capwell
This is a spin off of CASSANDRA-15313 and CASSANDRA-15539
This was found when lz4 sees compressed data (not all, but happens) which is
