---------------------------------
Summary: Add input format for stitching together multiple files
Key: ORC-291
URL: https://issues.apache.org/jira/browse/ORC-291
Project: ORC
Issue Type: Improvement
Reporter: Owen O'Malley
It would be useful to have the ability to have an InputFormat that stitches
together multiple files where the files have a 1:1 relationship for rows. If
the column name has appeared previously, its value will be used instead of the
original value. If the column name is new, it will be appended on to the row.
This will allow simple cases of appending or updating fields without re-writing
the file until later.
