With this feature, you can set up subscriptions to specific changes for an Entity – and DataHub will notify you when those changes happen. Currently, DataHub supports notifications on Slack and Email, with support for Microsoft Teams forthcoming.
Email will work out of box. For installing the DataHub Slack App, see:
👉 [Configure Slack for Notifications](slack/saas-slack-setup.md)
This feature is especially useful in helping you stay on top of any upstream changes that could impact the assets you or your stakeholders rely on. It eliminates the need for you and your team to manually check for upstream changes, or for upstream stakeholders to identify and notify impacted users.
As a user, you can subscribe to and receive notifications about changes such as deprecations, schema changes, changes in ownership, assertions, or incidents. You’ll always been in the know about potential data quality issues so you can proactively manage your data resources.
This requires appropriate permissions. Go to `Settings` > `Notifications` (under the `Platform` section, not `My Notifications`).
**Platform-level Notifications:**
Platform-level notifications are applied to all assets within Datahub.
Example: If "An owner is added or removed from a data asset" is ticked, the designated Slack channel or email will receive notifications for any such changes across all assets.
**Our Recommendations:**
Notifying on tag changes for every asset in the platform would be noisy, and so we recommend to use these platform-level notifications only where appropriate. For example, we recommend notifications for ingestion failures routed to a central Slack channel or email. This will help you proactively ensure your Datahub metadata stays fresh.
Once you have [configured Slack within your DataHub instance](slack/saas-slack-setup.md), you will be able to subscribe to any Entity in DataHub and begin recieving notifications via DM.
To begin receiving personal notifications, go to Settings > "My Notifications". From here, toggle on Slack Notifications and input your Slack Member ID.
If you want to create and manage group-level Subscriptions for your team, you will need [the following privileges](../../docs/authorization/roles.md#role-privileges):
DataHub’s [Lineage and Impact Analysis features](../../docs/act-on-metadata/impact-analysis.md#lineage-impact-analysis-setup-prerequisites-and-permissions) can help you identify upstream entities that could impact the assets you use and are responsible for.
You can use the Subscriptions and Notifications feature to sign up for updates for your entire team, or just for yourself.
### Subscribing Your Team/Group to Notifications
The dropdown menu next to the Subscribe button lets you choose who the subscription is for. To create a group subscription, click on Manage Group Subscriptions.
Connect to Slack. Currently, DataHub Cloud's Subscriptions and Notifications feature integrates only with Slack. Add your group’s Slack Channel ID to receive notifications on Slack.
You can enable, disable, or manage notifications at any time to ensure that you receive relevant updates.
Simply use the Dropdown menu next to the Subscribe button to unsubscribe from the asset, or to manage/modify your subscription (say, to modify the changes you want to be updated about).
You can always subscribe to _all assertion status changes_ on a table using the steps outlined in the earlier sections. However, in some cases you may want to only be notified about specific assertions on a table. For instance, a table may contain several subsets of information, segmented by a category column - so there may be several different checks for each category. As a consumer, you may only care about the freshness check that runs on one specific category of this larger table.
You can subscribe to individual assertions by clicking the bell button on the assertion itself - either in the list view:
