What does the Refresh Metadata button do?

Learn what the Refresh Metadata button does in the SQL Data Source Editor.

Open the SQL Data Source Editor

For SQL data sources, if using the visual editor (1), table/column metadata from the data base is collected periodically and cached on the Metric Insights server.  When users go into the Visual Editor from an Editor, the cached metadata is used instead of making a database hit to pull up table/column information.

The Refresh Metadata button (2) allows you to force the refresh of this metadata.
