Jimmy Xiang updated HBASE-8420:
-------------------------------
Attachment: trunk-8420_v1.patch
The patch is a little different from the original one in 0.89-fb. The reason
is that we have coprocessor supports and the scanner logic is a little
different. We have pb too.
> Port HBASE-6874 Implement prefetching for scanners from 0.89-fb
