Left comments in RB. > Fast stripe level merging for ORC > --------------------------------- > > Key: HIVE-7509 > URL: https://issues.apache.org/jira/browse/HIVE-7509 > Project: Hive > Issue Type: Bug > Affects Versions: 0.14.0 > Reporter: Prasanth J > Assignee: Prasanth J > Labels: orcfile > Attachments: HIVE-7509.1.patch, HIVE-7509.2.patch, HIVE-7509.3.patch > > > Similar to HIVE-1950, add support for fast stripe level merging of ORC files through CONCATENATE command and conditional merge task. This fast merging is ideal for merging many small ORC files to a larger file without decompressing and decoding the data of small orc files. -- This message was sent by Atlassian JIRA (v6.2#6252)
