Usage notes

  • The new OpenSearch console refines the permission granularity for RAM users. To use the new OpenSearch console as a RAM user, you must reconfigure the RAM authorization policy.

  • The RAM user feature requires SDK V3 or later.

  • To configure an ApsaraDB RDS data source as a RAM user in the OpenSearch console, the RAM user must have permissions to access ApsaraDB RDS. Without these permissions, the console returns a connection error and you must try again later. For details, see Access authorization rules.
