Notification service
The notification service enables Manufacturing Data Engine (MDE) to send notifications to
the user regarding updates in the processing status. This feature was
introduced in release v1.4.0 to enable a more convenient way for the user to
take action based on certain events without the need to manually check the logs.
In v1.4.0, this notification service has two different types of
notifications:
A warning, when a metadata natural-key instance count is approaching
the maximum limit (which is 200). This warning will be triggered when reaching 50% of
the maximum hard limit. The user can check the metadata warning
page to
filter through the natural keys that are approaching the deletion
limit.
A notification, when the metadata natural-key instances are actually
deleted from the MDE operational
datastore in order to ensure the system performance.
In the web interface, the notifications will show up in the top-right corner of the screen.
If you're using the Notification API, it supports the following operations:
Listing the reported notifications with the ability to filter by their
status (for example, read and unread).
Mark a notification as read.
Delete read notifications.
Delete all notifications.
Future releases of MDE might include more notification types
for a better user experience.
