Subject [jira] [Created] (HBASE-11497) Expose RpcScheduling implementations as Public Interfaces
Date Thu, 10 Jul 2014 19:22:04 GMT
Jesse Yates created HBASE-11497:
-----------------------------------

             Summary: Expose RpcScheduling implementations as Public Interfaces
                 Key: HBASE-11497
                 URL: https://issues.apache.org/jira/browse/HBASE-11497
             Project: HBase
          Issue Type: Improvement
          Components: io, regionserver, Usability
    Affects Versions: 0.99.0, 0.98.4
            Reporter: Jesse Yates


In Phoenix-938 we are attempting to resolve cross-RS deadlocks in indexing by adding custom
RPC handlers (so regular puts/reads don't interfere with index updates). However, we've run
into a couple of snags where the interfaces change, making it a bit more difficult to support
interoperability between minor versions as the underlying RPC handling changed (for the better,
but still different :).

This would just mark those interfaces Public, Evolving, so we still have some flexibility,
but don't break existing usage.

Note, this kind of thing will come up for any client who is doing custom RPC handling - beyond
the recently added flexibility - but wants to stay in line with the current HBase implementation
(rather than building their own RPC handling mechanisms).
