> 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?
