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.

Hi to all,
is there any performance degradation using Row instead of Tuple
objects in Flink?
Best,
Flavio
