*GET DATASET SUMMARY*
=====================

Computes a statistical summary (count, mean, min, max, std, etc.) for a dataset, optionally restricted to a selected subset of columns. Use this worker to quickly profile a dataset's schema and descriptive statistics before further processing or modelling.

When to use
-----------

Classification: **process**.
