ramkrishna.s.vasudevan commented on HBASE-10531:
------------------------------------------------
Did some benchmarks
Mainly took a reading with single node and ran YCSB for pure reads (gets) and
sequential scans.
The gets were averaged over 50 runs
Without patch
Throughput : 1418.42019 ops/sec
With patch
Throughput : 1422.117704
For scans averaged over 15 runs
Without patch
Throughput :351.0178049
With patch
Throughput : 351.4325864
Every run tries to perform 50000 operations. So overall I don't find much
difference in the working of reads with and without patch. I have take the
plain case(no encoding). I can add results with some encodings like Fast_diff
also.

> Currently the byte[] key passed to HFileScanner.seekTo and
> HFileScanner.reseekTo, is a combination of row, cf, qual, type and ts. And
> the caller forms this by using kv.getBuffer, which is actually deprecated.
> So see how this can be achieved considering kv.getBuffer is removed.
