Subject RE: Is there a way to only scan data in memstore
Date Thu, 21 Mar 2013 09:31:02 GMT
How you can be sure abt data will be in memstore only. What if in btw flush happening?   Which
version in use?
In 94.x version (I am not sure abt the .x version no#) there is preStoreScannerOpen() CP hook.
This impl can return a KVScanner for a store (In your impl the scanner can be only for Memstore?).
Pls see how this hook is being used and how the StoreScanner is being created.

Can you think of control this using TimeRange on Scan ?

I just want to scan data in memstore, but I saw InternalScan is private class.  Is there a
way i can do it without change the hbase source code?
