> Currently each txn using ACID insert/update/delete will generate a delta directory like
delta_0000100_0000101.  In order to support multi-statement transactions we must generate
one delta per operation within the transaction so the deltas would be named like delta_0000100_0000101_0001,
etc.
> Support for MERGE (HIVE-10924) would need the same.
