Amitanand Aiyer updated HBASE-4345:
-----------------------------------
Attachment: patch-3
To enforce the read-write consistency mechanism, we need to ignore all
key-values that have a memstoreTS greater than the read point for the get/scan
operation.
Filters provide an excellent mechanism to ignore values based on any desired
condition. We implement the RWCC mechanism for the key-values read from the
disk by including a filter for the scan object that ignores "newer" reads.
> Ensure that Scanners that read from the storefiles respect MVCC

> Currently, the key-values written to the disk do not include the MVCC (RWCC)
> version information. Once we add that
> information, and make it persistent to disk; let us make the scanners respect
> the MVCC mechanism by ignoring
> "newer" writes.
