> ----------------------------------------------------------------------------------

> Key: HIVE-4977
> URL: https://issues.apache.org/jira/browse/HIVE-4977
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Affects Versions: 0.10.0, 0.11.0, 0.12.0
> Reporter: Chris Drome
> Assignee: Chris Drome
>
> Current serialization protocol between client and server as defined in
> cli_service.thrift results in 2x (or more) throughput degradation compared to
> HS1.
> Initial proposal is to introduce HS1 serialization protocol as a negotiable
> alternative.
