Micah Kornfield created ARROW-6219:
--------------------------------------

             Summary: [Java] Add API for JDBC adapter that can convert less 
then the full result set at a time.
                 Key: ARROW-6219
                 URL: https://issues.apache.org/jira/browse/ARROW-6219
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Java
            Reporter: Micah Kornfield


Somehow we should configure number of rows per batch and either let clients 
iterate or provide an iterator API.  Otherwise for large result sets we might 
run out of memory.
