------------------------------------
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.
