Subject [jira] [Commented] (HBASE-12215) PrefixFilter should use SEEK_NEXT_USING_HINT
Date Thu, 09 Oct 2014 18:53:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14165538#comment-14165538
] 

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 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
