Lars Hofhansl commented on HBASE-11811:
---------------------------------------
I also just renamed the old blockSeek methods to blockSeekOld, obviously those
would be removed.
Looking through the code I noticed a lot of duplication betweek HFileReaderV2
and HFileReaderV3, this can probably factored a bit nicer generally.

> Currently upon every seek (including Gets) we need to linearly look through
> the block from the beginning until we find the Cell we are looking for.
> It should be possible to build a simple cache of offsets of Cells for each
> block as it is loaded and then use binary search to find the Cell in question.
