Subject [jira] [Commented] (HBASE-15243) Utilize the lowest seek value when all Filters in MUST_PASS_ONE FilterList return SEEK_NEXT_USING_HINT
Date Tue, 16 Feb 2016 07:42:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15243?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15148211#comment-15148211
] 

Ted Yu commented on HBASE-15243:
--------------------------------

The change in MultiRowRangeFilter was to deal with the following case:

MultiRowRangeFileter1    range: [10,15]
MultiRowRangeFileter2    range: [20, 25]
Row key: 16

Hint from Filter1 should be excluded since it is already done.

Patch v3 addresses the above scenario without modifying MultiRowRangeFilter since we cannot
produce row key which is guaranteed to be  greater than all other row keys.

> As Preston Koprivica pointed out at the tail of HBASE-4394, when all filters in a MUST_PASS_ONE
FilterList return a SEEK_USING_NEXT_HINT code, we should return SEEK_NEXT_USING_HINT from
the FilterList to utilize the lowest seek value.
