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

             Summary: Add new attribute to Scan to limit the return size of records
                 Key: HBASE-14294
                 URL: https://issues.apache.org/jira/browse/HBASE-14294
             Project: HBase
          Issue Type: Improvement
    Affects Versions: 2.0.0
            Reporter: congcong.han
            Assignee: congcong.han
            Priority: Minor
             Fix For: 2.0.0


Reason:
we all use PageFilter to limit the size of the return records,but the PageFilter return limit * region number size of limit ,which is bad for a huge number of region per table.
Solution:
ClientScanner has a attribute caching which determine the return size of record per RPC,so we can use this attribute to limit the return size of hbase.
