-------------------------------------
Summary: delete_deleta_x_x cannot modify delta_x_x
Key: HIVE-17127
URL: https://issues.apache.org/jira/browse/HIVE-17127
Project: Hive
Issue Type: Improvement
Affects Versions: 2.2.0
Reporter: Eugene Koifman
Assignee: 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.
