Till Rohrmann commented on FLINK-1901:
--------------------------------------
The problem is that a sampling operator should also work within iterations.
There is definitely a big need for this, e.g. for stochastic gradient descent.
I don't really understand what you mean with your question [~sachingoel0101].

> Key: FLINK-1901
> URL: https://issues.apache.org/jira/browse/FLINK-1901
> Project: Flink
> Issue Type: Improvement
> Components: Core
> Reporter: Theodore Vasiloudis
> Assignee: Chengxiang Li
>
> 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
> sample from a Dataset.
> 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.
