--------------------------------------
Hi, [~sachingoel0101], I didn't find any related class about sampling while
search the project with the keyword, is the PR you mentioned ongoing now?
Besides ML algorithms, there should be other use case depends on sampling
operation, such as range partition, and i believe sample operation itself is a
common operation which may be used directly by user.

> In order to be able to implement Stochastic Gradient Descent and a number of
> other machine learning algorithms we need to have a way to take a random

> We need to be able to sample with or without replacement from the Dataset,
> choose the relative size of the sample, and set a seed for reproducibility.
