Subject Re: Tuple vs Row
Date Sat, 08 Oct 2016 00:15:03 GMT
Hi Flavio,

I have never benchmarked Rows but they definitely add some overhead. 
Each new row also creates an array object storing the values, the 
serializer maintains a bitmask for tagging null values and the 
comparator has additional checks for null values.

Would be interesting to measure the performance degradation.
