> There are two issues that are causing invalid results:
> 1. In some conditions we are failing to add the record to current aggregation 
> workspace around batch boundary or output batch is full.
> 2. Incorrectly cleaning up the previous batch. Currently we keep a reference 
> to the current batch in "previous" and try to get the next incoming batch 
> which has more than zero records or there are no incoming batches. If the 
> next incoming batch has zero records, we are cleaning up the "previous" batch.
