---------------------------------------

             Summary: Make SSTABLESCRUB and related jobs multi-threaded  / parallelize somehow
                 Key: CASSANDRA-11324
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11324
             Project: Cassandra
          Issue Type: Improvement
          Components: Tools
            Reporter: Thom Valley
            Priority: Minor


SSTABLE scrub right now appears to be single threaded in offline mode (unsure about online).
 When scrubbing a node, especially a well provisioned one, the node sits mostly idle for potentially
hours while scrubbing.

Making better use of available resources through parallelization / multi-threading of the
scrub process seems like a good idea.
