> 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.
