Data Platform

Data Platforms are systems or tools that contain Datasets, Dashboards, Charts, and all other kinds of data assets modeled in the metadata graph.

Examples of data platforms are redshift, hive, bigquery, looker, tableau etc.

Identity​

Data Platforms are identified by the name of the technology. A complete list of currently supported data platforms is available here.
