Lars Hofhansl commented on HBASE-12215:
---------------------------------------
Can you elaborate?
PrefixFilter has to be used in conjunction with setting the startRow on the
scan to the prefix. The range of row with the same prefix is already
contiguous. Where would we benefit from seeking with a hint?
It's possible I am missing something.
> PrefixFilter should use SEEK_NEXT_USING_HINT

> Affects Versions: 0.98.6.1
> Reporter: Brian Johnson

> PrefixFilter is really just a specialized case of FuzzyFilter. It could be
> implemented on top of it, but at the very least it should take advantage of
> SEEK_NEXT_USING_HINT for performance reasons
