Review Comment:
Normal compaction is not blocking (Uses SHARED_READ lock) so there is no
need for conflict detection. Rebalance compaction uses EXCL_WRITE lock, and the
records must not moved to the complete table in order to be able to detect
conflicting write attempts. This is required to force concurrent
updates/deletes to re-create their plan and use the new base/deltas containing
the changed ACID rows.
