Subject [jira] [Commented] (HIVE-3585) Integrate Trevni as another columnar oriented file format
Date Tue, 08 Jan 2013 19:04:15 GMT


Sean Busbey commented on HIVE-3585:

@Namit My earlier comment was meant to answer this

Trevni defines a columnar format that can be used with different serialization systems. I
believe initial efforts across different components are planning to use Avro for serialization.

Eventually, Trevni support should also work for Thrift and Protobufs.

In short, Trevni always requires a serialization format. Current efforts across components
are focused on Avro as the first implementation. With that, users will need access to the
Avro libraries.

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.
