URL: https://github.com/apache/drill/pull/1255
 
 
   union all transfers the complete incoming batches as is. With this change, a single batch will be split into multiple output batches if needed, based on batch size. Added support to split and transfer as many rows that fit per memory budget i.e. as per configured output batch size. 
   This PR also has fix for 
   DRILL-6402: Repeated Value Vectors copyFrom methods are not updating the value count and writer index correctly for values vector.
