Subject [jira] [Commented] (HIVE-3585) Integrate Trevni as another columnar oriented file format

Jakob Homan commented on HIVE-3585:
-----------------------------------

Also, He, I'm assuming your -1 is not intended to be a veto? I don't believe it would hold
up technically.  Trevni is essentially a variation on Avro.  Not letting people read their
Trevni-encoded data in Hive just because there's already another columnar format doesn't seem
like a good way forward.

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.
