             Summary: Use NavigableSet to store rowkey and use prefix filter to check resource path prefix instead String comparison on tomcat side
                 Key: KYLIN-1504
                 URL: https://issues.apache.org/jira/browse/KYLIN-1504
             Project: Kylin
          Issue Type: Sub-task
    Affects Versions: v1.3.0, v1.4.0
            Reporter: Hao Chen
            Assignee: Hao Chen
             Fix For: v1.5.1


- Use NavigableSet<String> instead ArrayList<String> to store natively ordered and unique row-key instead of ugly repeatedly using `Collections.sort` or check whether existing on business logic layer, in fact because the raw-key is originally sorted in hbase, the change won't consume any more computational complexity.
- Verify prefix in hbase region level using prefix filter instead of comparing String in client side.
