Todd Lipcon commented on HBASE-5889:
------------------------------------
I'm just not sure this is actually the best bang for the buck, and might make
layering less clean. I'm looking at RS CPU usage right now and the protobuf
conversion doesn't show up at all in oprofile results. Finding a number of
other hotspots for this kind of workload, though (see other JIRAs I'm filing)
> Remove HRegionInterface

> Key: HBASE-5889
> URL: https://issues.apache.org/jira/browse/HBASE-5889
> Project: HBase

> Components: client, ipc, regionserver
> Affects Versions: 0.96.0
> Reporter: Jimmy Xiang
> Assignee: Jimmy Xiang
> Fix For: 0.96.0
>
>
> As a step to move internals to PB, so as to avoid the conversion for
> performance reason, we should remove the HRegionInterface.
> Therefore region server only supports ClientProtocol and AdminProtocol.
> Later on, HRegion can work with PB messages directly.
