>                 URL:
>             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.
