Duo Zhang updated HBASE-19033:
------------------------------
Attachment: HBASE-19033.patch
An initial version to show the new APIs. As said before, add the three methods
again without a return value
preFlushScannerOpen, preCompactScannerOpen, preStoreScannerOpen.
Introduce a ScanOptions interface to let CP users change the max versions and
TTL of a ScanInfo.
The new example 'WriteHeavyIncrementObserver' has not been finished yet. Will
upload a new patch once I finish it.
Thanks.
> Allow CP users to change versions and TTL before opening StoreScanner
