Subject [jira] [Commented] (HBASE-6787) Convert RowProcessorProtocol to protocol buffer service
Date Wed, 14 Nov 2012 23:00:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6787?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13497562#comment-13497562

Devaraj Das commented on HBASE-6787:
------------------------------------

bq. between this and the ColumnInterpreter stuff for AggregateService, we seem to be working
towards a common interface for the user code serialization/deserialization bits

Yeah.. that's true. Should we move this work to a different jira (where we make the relevant
changes for the other coprocessor implementations as well).

bq. But I think we're adding some complexity to remain serialization agnostic in this case.
Is the need there to make the trade off worth it?

I am not sure if we should enforce PB for users to be able to use the coprocessor service,
but I can go either way, and yeah doing pure PB everywhere (in framework & user code)
would probably make the implementation of the framework code simpler. Will take a pass at
it...

> With coprocessor endpoints now exposed as protobuf defined services, we should convert
over all of our built-in endpoints to PB services.
