> Support external ZSTD dictionary in CQLSSTableWriter
> ----------------------------------------------------
>
> Key: CASSANDRA-20938
> URL: https://issues.apache.org/jira/browse/CASSANDRA-20938
> Project: Apache Cassandra
> Issue Type: New Feature
> Components: Legacy/Core
> Reporter: Yifan Cai
> Assignee: Stefan Miklosovic
> Priority: Normal
> Fix For: 5.x

> Remaining Estimate: 0h

> Extend CQLSSTableWriter to accept an external ZSTD compression dictionary for
> writing SSTables.
> - Add a new option to pass the dictionary.
> - Dictionary is only applied if the table schema indicates ZSTD compression
> with dictionary enabled.
> - Document best practices: external tooling invoking CQLSSTableWriter should
> fetch the current dictionary from Cassandra to avoid excessive dictionary
> proliferation.
