> Key: CASSANDRA-19900
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19900

> Components: Analytics Library
> Reporter: James Berragan

> Remaining Estimate: 0h

> Normally the CompressionInfo.db file is trivial in size (a few kb) and so can
> be easily cached to prevent wasteful requests for the same file, but for
> large SSTables (running into a few hundred GB, due to schema issues or large
> blobs) then the {color:#000000}CompressionInfo.db files can also grow to be a
> few hundred MB or GB making it problematic to cache. We should make the
> compression cache optional and configurable so we don’t cache large
> files.{color}
