Subject [jira] [Commented] (HBASE-5950) Add a decimal comparator for Filter
Date Mon, 24 Sep 2012 11:12:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13461734#comment-13461734

Jieshan Bean commented on HBASE-5950:
-------------------------------------

This comparator is not needed if we store the Integer/Double/Float as bytes directly. Right?

>             Project: HBase
>          Issue Type: New Feature
>          Components: Filters
>    Affects Versions: 0.94.0, 0.96.0

> Suppose we have a requirement like below:
> we want to get the rows with one specified column value larger than A and less than B.
> (They are all decimals or integers)
> namely:                         
>        A < Integer.valueof(column) < B
> Use BinaryComparator will not help us to archive that goal:
> e.g.   suppose A = 100, B = 200, one column value is 110000.
>    So it can satisfy that condition, but it's not the row we wanted.
>     	   
> So I suggest to add one comparator to help implementing this.
