Subject [jira] [Updated] (HIVE-3133) Implement map-side non-equi join
Date Wed, 13 Jun 2012 20:37:42 GMT


Carl Steinbach updated HIVE-3133:

    Component/s: Query Processor
> Implement map-side non-equi join
> --------------------------------
>                 Key: HIVE-3133
>                 URL:
>             Project: Hive
>          Issue Type: Improvement
>          Components: Query Processor, SQL
>            Reporter: Navis
>            Priority: Minor
> It's rather simple to implement non-equi join in mapjoin by replacing hashmap to treemap,
if it's targeted for single column. And if it's targeted two or more columns we can facilitate
lucene file for lookup in mapjoin operator.
> I wish I could provide the patch but it's not my decision by contract. I believe someone
can implement this for public use.
