  • GET /api/2.1/unity-catalog/catalogs: To get available catalogs.
  • GET: /api/2.1/unity-catalog/schema?catalog_name=main: To get schema from available catalogs.
  • GET: /api/2.1/unity-catalog/tables?catalog_name=main&schema_name=default: To get tables and views from a catalog schema.
  • GET: /api/2.1/unity-catalog/tables/main.default.table_name: To get tables and views metadata.
