Package io.cdap.cdap.api.dataset Description

Defines APIs for accessing and managing data within CDAP.

Implement DatasetDefinition or Dataset to define custom data set types.

Otherwise, use pre-packaged types available in the io.cdap.cdap.api.dataset.lib and io.cdap.cdap.api.dataset.table packages.
