Subject [jira] [Commented] (HBASE-12215) PrefixFilter should use SEEK_NEXT_USING_HINT
Date Fri, 10 Oct 2014 02:33:34 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14166182#comment-14166182

Brian Johnson commented on HBASE-12215:
---------------------------------------

We want to pick out a subset of rowkey prefixes. In our case the row key is user_id|event_id
and we want to retrieve all the events for a subset of users. I don't believe that's possible
with FuzzyRowFilter. Phoenix's SkipScanFilter does what we want and is blazingly fast, but
requires defining Phoenix metadata for the tables and we really want something that works
with thrift/rest for our non-java applications.

> 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
