Eugene Koifman created HIVE-17127: ------------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
