Subject [jira] [Created] (CASSANDRA-7482) COPY FROM and COPY TO performance could be better
Date Tue, 01 Jul 2014 08:58:24 GMT
Jan Penninkhof created CASSANDRA-7482:
-----------------------------------------

             Summary: COPY FROM and COPY TO performance could be better
                 Key: CASSANDRA-7482
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7482
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Jan Penninkhof
            Priority: Minor
             Fix For: 2.0.10


The current COPY command seems to do its job in a single thread. However, the process could
benefit a lot from a multi-threaded version. E.g. we have created substitutes for the COPY
command that are > 20x as fast, by using executeAsync on inserts.

In case a multi-threaded version would introduce new risks, perhaps it would be possible to
add this as a feature that could be switched on with an statement option.
