Amazon RDS - System Upgrade Notification for MySQL and PostgreSQL

Amazon AWS sent official mailling this morning, all AWS RDS instances will receive mendatory upgrade next month. Further information below:

-------------------------------------------------

Dear Amazon RDS Customer,

All Amazon RDS for MySQL and PostgreSQL database instances have been scheduled to receive mandatory system upgrade as per the schedule below during the maintenance window you defined for them. For example, if you have chosen Thursday 16:00 UTC with a duration of 30min as the maintenance window for your database instance in the US West (N. California) Region, it will receive the system upgrade on 16 October 2014 (Thursday) between 16:00 UTC and 16:30 UTC.

Please note that while the upgrade completes, your DB Instance will have an availability impact for a few minutes during your maintenance window (even if you chose “No” for the “Auto Minor Version Upgrade” option). Therefore, please cross check your maintenance window settings to ensure that they are set as per your needs using the schedule above. For Multi-AZ deployments, upgrade first occurs on your standby node, followed by a failover, limiting your availability impact to typically 60 - 120 seconds. You can subscribe to Event Notifications ( http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_Events.html ) for the “Maintenance” Category to receive notifications when your instance gets upgraded.

Note that this maintenance schedule is only applicable for MySQL and PostgreSQL database instances. Also, any MySQL or PostgreSQL database instance created after 29 Sep 2014 00:00 UTC will already have this upgrade and will not be impacted by this maintenance. Lastly, if you are using MySQL 5.6, you may want to evaluate turning on InnoDB Cache Warming ( http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_MySQL.html#MySQL.Concepts.InnoDBCacheWarming ) and dumping the buffer pool before the upgrade to improve read latency after your instance restarts.

Should you have any questions or concerns, the AWS Support Team is available on the community forums and via AWS Support Portal.
