[jira] [Created] (HBASE-15498) Add conditions in MultiRowMutationService

He Liangliang created HBASE-15498:
-------------------------------------

             Summary: Add conditions in MultiRowMutationService
                 Key: HBASE-15498
                 URL: https://issues.apache.org/jira/browse/HBASE-15498
             Project: HBase
          Issue Type: New Feature
          Components: Coprocessors
            Reporter: He Liangliang


Many applications especially online services need conditional batch operations to achieve atomicity. We can add conditions in MultiRowMutationService like:
<code>
message MutateRowsRequest {
  repeated MutationProto mutation_request = 1;
  optional uint64 nonce_group = 2;
  optional uint64 nonce = 3;
  repeated Condition condition = 4;
}

message MutateRowsResponse {
  repeated int32 unmet_conditions = 1;
}

service MultiRowMutationService {
  rpc MutateRows(MutateRowsRequest)
      returns(MutateRowsResponse);
}
</code>
