-----------------------------------------
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.
