-----------------------------------

             Summary: [C++] Add hash-join support for large-offset types (e.g. 
large_string) and dictionary encoded types to the new hash-join impl
                 Key: ARROW-16224
                 URL: https://issues.apache.org/jira/browse/ARROW-16224
             Project: Apache Arrow
          Issue Type: Improvement
          Components: C++
            Reporter: Weston Pace


The current proposal for the improved hash-join does not support using large 
binary types (those with 8 byte offsets) or dictionary types as key columns.  
We should support those.
