[jira] [Resolved] (IMPALA-2471) Investigate HS2 Thrift efficiency

     [ https://issues.apache.org/jira/browse/IMPALA-2471?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tim Armstrong resolved IMPALA-2471.
-----------------------------------
    Resolution: Later

This has been idle a long time. I think IMPALA-8656 and other improvements probably helped here.

>                 URL: https://issues.apache.org/jira/browse/IMPALA-2471
>             Project: IMPALA
>          Issue Type: Task
>          Components: Backend
>    Affects Versions: Impala 2.2.4
>            Reporter: Alan Choi
>            Priority: Minor
>
> There are some known performance issues with the current HS2 thrift protocol:
> 1. Large overhead ~60%
> This is unacceptably large.
> 2. Slow network throughput ~10MB/sec only
> Even though the HS2 client is co-located with the server, the throughput is max out at ~10MB/sec
