Russell Jurney commented on HIVE-3585:
--------------------------------------

He, HCatalog uses Hive Serde. By adding the Trevni builtin for Apache Hive, 
Apache Hive, Shark, Apache HCatalog and Apache Pig will all get Trevni support. 
Synergy, baby!

Apache Trevni is part of an actual Apache top-level project, Apache Avro, so it 
is nothing like Zebra, which I notice you reported yourself for addition in 
HIVE-781. Avro and Trevni are specifically designed for Hadoop workloads, and 
other tools like Pig are including Trevni immediately.

                
> Integrate Trevni as another columnar oriented file format

> need a columnar 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.
