----------------------------------------
Summary: Enhance Zstd support in Cassandra with dictionaries
Key: CASSANDRA-17021
URL: https://issues.apache.org/jira/browse/CASSANDRA-17021
Project: Cassandra
Issue Type: Improvement
Components: Feature/Compression
Reporter: Dinesh Joshi
Assignee: Yifan Cai
Currently Cassandra supports zstd compression. However, Zstd also supports
dictionaries to enhance not only the compression ratio but also the speed.
Dictionaries can show 3-4x savings. We should add support to train
dictionaries, ideally per SSTable this will yield the maximum gains.
