------------------------------------

sc has commented on the revision "HBASE-5515 [jira] Add a processRow API that supports atomic multiple reads and writes on a row".

  Ted: Yes, this API allows read-modify-write atomically. Also you can perform multiple reads with dependency on previous results (for example, querying friends of friends in the unit test).
