Subject [jira] [Updated] (HIVE-3585) Integrate Trevni as another columnar oriented file format
Date Tue, 29 Jan 2013 22:11:14 GMT


Mark Wagner updated HIVE-3585:

    Attachment: futurama_episodes.avro

Patch attached. Some notes:
* This patch implements a SerDe for Avro wrapped Trevni, which allows it to be implemented
as a separate file format for the existing AvroSerDe
* This patch contains contributions from Srinivas Vemuri derived from uncommitted patches
to Haivvreo
* Avro version has been bumped to 1.7.3 to bring in trevni
* trevni-avro and trevni-core modules of Avro are now included
* The test avro_partition_format.q has no corresponding *.q.out file due to HIVE-3953. What's
the best way to handle this test? Include it knowing it will fail, wait until HIVE-3953 is
resolved to commit, or another option?

SerDe,seems fastutil is a good choice.the shark project use fastutil library as columnar serde
library but it seems too large (almost 15m) for just a few primitive array collection.
