It is a huge challenge to inform the data team about upcoming changes to data. In most organizations, data changes are announced in advance over email or Slack; and sometimes, this information is noticed pretty late, leaving very little time to prepare for the changes.
In OpenMetadata, announcements can be set up to inform the entire team about the upcoming changes to a data asset. With the Announcements feature, you can now inform your entire team of all the upcoming events and changes, such as deprecation, deletion, or schema changes. These announcements can be scheduled with a start date and an end date. All the users following your data are not only notified in Activity Feeds but a banner is also shown on the data asset details page.
Tip: Ideally, it’s best to schedule the announcements well in advance before modifying or deleting a data asset, so you can ensure that the entire team has a reasonable amount of time to plan accordingly.

Pro Tip: Ensure that all backward incompatible changes are announced to the team well in advance. For example, when deleting a column from a table.
Clicking on the announcement will display further details.

Details of an Announcement
Details of an announcement are as follows:
- Creator: Get to know who added the announcement.
- Data Asset: Know the data asset type (Table, Pipeline) as well as name of the data asset it pertains to.
