---------------------------------------
Summary: Allow configuration of inter DC compression
Key: CASSANDRA-12017
URL: https://issues.apache.org/jira/browse/CASSANDRA-12017
Project: Cassandra
Issue Type: Improvement
Reporter: Thom Valley
With larger and more extensively geographically distributed clusters, users are
beginning to need the ability to reduce bandwidth consumption as much as
possible.
With larger workloads, the limits of even large intercontinental data links
(55MBps is pretty typical) are beginning to be stretched.
InterDC SSL is currently hard coded to use the fastest (not highest)
compression settings. LZ4 is a great option, but being able to raise the
compression at the cost of some additional CPU may save as much as 10% (perhaps
slightly more depending on the data). 10% of a 55MBps link, if running at or
near capacity is substantial.
This also has a large impact on the overhead and rate possible for
instantiating new DCs as well as rebuilding a DC after a failure.
