Dataset statistics

Hi to all,
is there any effort to standardize descriptive statistics in Apache Flink?
Is there any suggested way to achieve this?

Best,
Flavio

We've just published a first attempt (on Flink 1.6.2) that extract some
descriptive statistics from a batch dataset[1].
Any feedback is welcome.

Best,
Flavio

No effort in this direction, then?
I had a try using SQL on Table API but I fear that the generated plan is
not the optimal one..I'm looking for an efficient way to implement
describe() method on a table or dataset/datasource
