-------------------------------------------
Summary: Add byte array backed cells
Key: CASSANDRA-15393
URL: https://issues.apache.org/jira/browse/CASSANDRA-15393
Project: Cassandra
Issue Type: Sub-task
Components: Local/Compaction
Reporter: Blake Eggleston
Assignee: Blake Eggleston
We currently materialize all values as on heap byte buffers. Byte buffers have
a fairly high overhead given how frequently they’re used, and on the compaction
and local read path we don’t do anything that needs them. Use of byte buffer
methods only happens on the coordinator. Using cells that are backed by byte
arrays instead in these situations reduces compaction and read garbage up to
22% in many cases.
