Note that, you can add as many MySQL server endpoint configurations as needed by providing an identifier (like "myinstance" in the example above) for each MySQL instance desired.

Restart the MinIO server to put the changes into effect. The server will print a line like `SQS ARNs: arn:minio:sqs::myinstance:mysql` at start-up, if there are no errors.
