Expand description

CDRS support traffic decompression as it is described in Apache Cassandra protocol

Before being used, client and server must agree on a compression algorithm to use, which is done in the STARTUP message. As a consequence, a STARTUP message must never be compressed. However, once the STARTUP frame has been received by the server, messages can be compressed (including the response to the STARTUP request).
