[jira] [Created] (CASSANDRA-21034) ZstdDictionaryCompressor is not used upon flush

Stefan Miklosovic created CASSANDRA-21034:
---------------------------------------------

             Summary: ZstdDictionaryCompressor is not used upon flush
                 Key: CASSANDRA-21034
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-21034
             Project: Apache Cassandra
          Issue Type: Bug
          Components: Feature/Compression
            Reporter: Stefan Miklosovic


When I insert data to a table and do {{nodetool flush}}, an SSTable is created, but it will be compacted with LZ4 (seen via sstablemetadata). Correct compressor should be used upon flush as well so flushed data are compressed by a Zstd dictionary too.
