> [Compaction Optimiziation]
> We should analyse the possibility to move a delta file instead of running a
> major/minor compaction query.
> Please consider the following use cases:
> - full acid table but only insert queries were run. This means that no
> delete delta directories were created. Is it possible to merge the delta
> directory contents without running a compaction query?
> - full acid table, initiating queries through the streaming API. If there
> are no abort transactions during the streaming, is it possible to merge the
> delta directory contents without running a compaction query?
