Review Comment:
I basically wanted to benchmark the execution with different batch sizes but
with the same total data amount. So, if we want to benchmark on batches with
10 rows each, then we should have 100000 batches, thus in total we will have
10000000 data points. Keeping the total data fix, the benchmarking tries to see
how the execution gets affected when we execute the same amount of data but
with batches of different sizes.
