Subject [jira] [Reopened] (HBASE-16303) FilterList with MUST_PASS_ONE optimization
Date Fri, 05 Aug 2016 20:34:20 GMT

     [ https://issues.apache.org/jira/browse/HBASE-16303?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sean Busbey reopened HBASE-16303:
---------------------------------

I had to revert the addendum from branch-1.3 because it broke compilation. I left the base
patch in place, because TestFilter and TestFilterList passed without the addendum. Please
verify that things are fine on branch-1.3 and then re-close.

> This JIRA was created to add @Test tag for all the filter related tests. After doing
that one such test failed in TestFilterList#testFilterListTwoFiltersMustPassOne.
> The test assumes that when a PrefixFilter is added to a filterlist once the given prefix
is passed we should SKIP all other rows. But the impl in FilterList for MUST_PASS_ONE filter
is such that once the filter in the list sees that filterAllRemaining is true we don't use
that to decide if to to SEE_NEXT_USING_HINT or not. This patch tries to handle that case where
if for a filter FilterAllRemaining is true then SEEK_NEXT_USING_HINT need not be done.
