>                 URL: https://issues.apache.org/jira/browse/HIVE-17127
>             Project: Hive
>          Issue Type: Improvement
>    Affects Versions: 2.2.0
>            Reporter: Eugene Koifman
>            Priority: Minor
>
> with split update an update statement will produce delete_deleta_x_x and delta_x_x for
any auto commit txn.  For multi-statement txn delete_delta_x_x_k may modify delta_x_x_j for
j < k.
> Since we generate splits from delta_x_x there may be a small optimization here.
