Note: Datasets are deprecated and will be removed in CDAP 7.0.0.
Datasets store and retrieve data. Datasets are your means of reading from and writing to the CDAP’s storage capabilities. Instead of forcing you to manipulate data with low-level APIs, datasets provide higher-level abstractions and generic, reusable implementations of common data patterns.

CDAP supports configuring impersonation at a namespace and at an application level, with application level configuration having a higher precedence than namespace level.
