Engine Releases for Amazon Neptune

Amazon Neptune releases engine updates regularly. Updates are applied to Neptune DB clusters during system maintenance windows. The timing of when updates are applied depends on the AWS Region and maintenance window setting for the DB cluster, and the type of update.

You can determine which engine release version you currently have installed using the instance-status API.

Updates are applied to all instances in a DB cluster simultaneously. An update requires a database restart on all instances in a DB cluster, so you will experience downtime ranging from 20–30 seconds to several minutes, after which you can resume using your DB cluster or clusters.

You can view or change your maintenance window settings on the Neptune console. For more information, see Neptune Maintenance Window.
