---------------------------------------
Summary: Repl rename support adds unnecessary duplication for
non-rename alters
Key: HIVE-15533
URL: https://issues.apache.org/jira/browse/HIVE-15533
Project: Hive
Issue Type: Sub-task
Reporter: Sushanth Sowmyan
Assignee: Sushanth Sowmyan
Currently, the rename events contain a before & after object. For non-rename
cases, we simply impress the "after" object, and thus have no need of the
"before" object. Thus, we might want to minimize wastage by not materializing
"before" if this is a non-rename case.
Also worth considering - if a rename case, do we really need the before object,
or simply the before & after names?
Having before & after objects is good in that it allows us flexibility, but we
might not need that much info. From a perf viewpoint, we might want to trim
things a bit here.
