Applications that are created after April 5, 2021 no longer support ApsaraDB RDS data sources in the classic network. If your applications require automatic synchronization of full or incremental data, configure ApsaraDB RDS data sources in virtual private clouds (VPCs) for your applications. We recommend that you change the data sources of your existing applications to ApsaraDB RDS data sources in VPCs at the earliest opportunity. Otherwise, your further use of OpenSearch may be affected. For more information, see Announcement about unpublishing ApsaraDB RDS data sources in the classic network.
