Using Integrated Data Lake (IDL) Data Sources in Dashboard Designer Add On

IDL data sources are accessible in the data sources drop-down list when you create a new panel and select a visualization, or when you create or edit a query. This allows you to:

  • Bring CSV and Parquet data in from IDL
  • Visualize multiple IDL queries in one widget
  • Visualize IoT and IDL data in one widget

IDL Data Source Limitations

  • Annotations are not supported for IDL data sources.
  • A maximum of 4,000 records is supported in IDL queries.
  • Aggregated data is not currently supported in queries, but is planned for a future release. The exception is the Gague widget, which auto-aggregates the data returned by a query.
  • A query time range of up to five years is supported.
  • Access controls may not extend to all data in IDL files and folders. For example, if two IDL files with access restrictions reside within an IDL folder that is unrestricted, and a user queries the unrestricted folder, all the files are returned, irrespective of restrictions on the IDL files or the user who creates the query.
  • IDL data sources do not support annotations.
