Amazon DocumentDB (with MongoDB compatibility) now supports maintenance notifications
[Amazon DocumentDB](https://aws.amazon.com/documentdb/) (with MongoDB compatibility) now adds support for maintenance notifications to provide users visibility into scheduled maintenance activities on their Amazon DocumentDB clusters. Users can now receive near real time notifications of scheduled maintenance activities through health events in AWS Health Dashboard (AHD) in AWS console and through emails. Amazon DocumentDB periodically releases maintenance patches containing critical security fixes, bug fixes, and enhancements. When an Amazon DocumentDB maintenance patch becomes available in an AWS region, all user accounts in the region will receive an AHD and e-mail notification for each Amazon DocumentDB version that patch applies to. The notifications will be available under ‘Scheduled Changes’ section of the AHD and will include details about patch availability, auto apply schedule, impacted clusters, and release notes. The notifications will also be delivered via e-mail to the AWS account’s root user email address. Additionally, users can programmatically respond to these notifications by configuring [Amazon EventBridge rules](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-rules.html) for "AWS\_DOCDB\_DB\_PATCH\_UPGRADE\_MAINTENANCE\_SCHEDULED" event type and choosing from 20+ supported targets, including AWS Lambda. For example, users can configure an Amazon Eventbridge rule to [send these maintenance notifications to AWS chatbot](https://docs.aws.amazon.com/chatbot/latest/adminguide/create-eventbridge-rule.html). AHD requires no setup and is available for use for all instance based Amazon DocumentDB users at no cost.
