>
> Currently the Acid compactor is implemented as generated MR job
> ({{CompactorMR.java}}).
> It could also be expressed as a Hive query that reads from a given partition
> and writes data back to the same partition. This will merge the deltas and
> 'apply' the delete events. The simplest would be to just use Insert
> Overwrite but that will change all ROW__IDs which we don't want.
> Need to implement this in a way that preserves ROW__IDs and creates a new
> {{base_x}} directory to handle Major compaction.
> Minor compaction will be investigated separately.
