A stream enables users to read and/or publish apps, sheets, and stories. Users who have publish access to a stream create the content for that specific stream. The stream access pattern on a Qlik Sense site is determined by the security rules for each stream. By default, Qlik Sense includes two streams: Everyone and Monitoring apps.
An app can be published to only one stream. However, if you duplicate the app to create a copy, you can publish the copy to another stream. Apps can be moved between streams.
In the hub, streams with no apps—either empty streams or streams that do not show apps due to the existing security rules for a user—will not appear. After you publish an app, move it from another stream, or delete it, the list of streams will update dynamically and the stream will appear in the hub or be hidden depending on whether it contains at least one app. Changes outside of the hub, for example in QMC, will not trigger an update to the stream list in the hub.
