    Description

      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.
