Eugene Koifman created HIVE-7513: ------------------------------------ Summary: Add ROW__ID VirtualColumn Key: HIVE-7513 URL: https://issues.apache.org/jira/browse/HIVE-7513 Project: Hive Issue Type: Sub-task Components: Query Processor Affects Versions: 0.13.1 Reporter: Eugene Koifman Assignee: Eugene Koifman
In order to support Update/Delete we need to read rowId from AcidInputFormat and pass that along through the operator pipeline (built from the WHERE clause of the SQL Statement) so that it can be written to the delta file by the update/delete (sink) operators. The parser will add this column to the projection list to make sure it's passed along. -- This message was sent by Atlassian JIRA (v6.2#6252)
