Lars Hofhansl updated HBASE-9807:
---------------------------------
Attachment: 9807-0.94.txt
Proposed patch. Pushes the compare into the scanner/seeker.
* in ScannerV2 that removes creation of the two ByteBuffer objects per reseek.
No real performance gain from that.
* in EncodedScannerV2 this avoid copying the entire key, just to compare it.
For 8 byte row keys and 10 bytes values this lead to a 10% performance gain in
scanning.
> scanning with block encoding unnecessarily copies the key for each reseek
