Subject [jira] [Commented] (HBASE-10463) Filter on columns containing numerics yield wrong results
Date Tue, 04 Feb 2014 18:18:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10463?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13890960#comment-13890960

Nick Dimiduk commented on HBASE-10463:

FYI, 0.96+ includes the OrderedBytes encoding format. Values encoded using those methods are
intended to order according to their natural order. Thus, the lexicographical byte-based comparators
should work with them directly.

>                 Key: HBASE-10463
>                 URL: https://issues.apache.org/jira/browse/HBASE-10463
>             Project: HBase
>          Issue Type: Improvement
>          Components: Filters
>    Affects Versions: 0.94.8
>            Reporter: Deepa Vasanthkumar
>   Original Estimate: 168h
>  Remaining Estimate: 168h
> Used SingleColumnValueFilter with CompareFilter.CompareOp.GREATER_OR_EQUAL for filtering
the scan result. 
> However the columns which have numeric value, scan result is not correct, because of
lexicographic comparison.
> Does HBase support numeric value filters (for equal, greater or equal..) for columns
? If not, can we add it?
