Important

New database features are no longer connected to engine versions; features are now enabled independently during scheduled update windows, and “major” and “minor” releases no longer exist in Helios. Please visit the release notes to view the latest features available in your database clusters.

The following example displays the connection links to the Orderdb database:

SHOW LINKS ON Orderdb;

| product_S3        | S3   | Products ordered in December    | {"region":"us-east-1"} |
+-------------------+------+---------------------------------+------------------------+

You can also query the information schema to view all links in the cluster, along with the link details.

SELECT * FROM INFORMATION_SCHEMA.LINKS;
+---------------+------------+------+------------------------------+-----------------------------+
| DATABASE_NAME | LINK       | TYPE | DESCRIPTION                  | CONFIG                      |
+---------------+------------+------+------------------------------+-----------------------------+
