 Review comment:
   It will not make it bigger. It will look at remaining memory and adjust the 
row count based on that. 
   
       final long remainingMemory = Math.max(configOutputBatchSize - 
memoryUsed, 0);
       // These are number of rows we can fit in remaining memory based on new 
outgoing row width.
       final int numOutputRowsRemaining = 
RecordBatchSizer.safeDivide(remainingMemory, newOutgoingRowWidth);
