Qubole Maintenance - RDS Upgrade - api.qubole.comWhat is changing?
Periodically, Amazon RDS performs maintenance on Amazon RDS resources. Maintenance most often involves updates to the DB instance's underlying operating system (OS) or database engine version. Updates to the operating system most often occur for security issues and should be done as soon as possible.
