                 Key: HBASE-11245
                 URL: https://issues.apache.org/jira/browse/HBASE-11245
             Project: HBase
          Issue Type: Task
            Reporter: Ted Yu
            Priority: Minor


When user table has large number of rows, one type of query is to select top N rows based
on matching column(s).

Aggregations Protocol (along with AggregateImplementation and AggregationClient) should support
this use case.
