Periodically, Neptune Analytics performs maintenance on Neptune resources. Maintenance most often involves updates to the following resources in your graph:
-
Underlying hardware
-
Underlying operating system (OS)
-
Graph engine version
Neptune Analytics doesn’t have a maintenance window for the graphs. It automatically performs maintenance operations which require the Neptune service to take your graph offline for a short time. Maintenance items that require a resource to be offline include required operating system or engine patching. Required patching is automatically scheduled only for patches that are related to security and instance reliability. Such patching occurs infrequently, typically once every few months. There are no actions required from the users for this to take place.
