---------------------------------
Summary: Stripe-level merge for ORC files
Key: HIVE-4221
URL: https://issues.apache.org/jira/browse/HIVE-4221
Project: Hive
Issue Type: Improvement
Components: Query Processor
Reporter: Samuel Yuan
Assignee: Samuel Yuan
As with RC files, we would like to be able to merge ORC files efficiently by
reading/writing stripes without decompressing/recompressing them. This will be
similar to the RC file merge, except that footers will have to be updated with
the stripe positions in the new file.
