Tasks

Tasks are used to perform a wide variety of operations and can be chained together in any arbitrary pattern. The tasks are handled by the Qlik Sense Scheduler Service (QSS) and managed in the Qlik Management Console (QMC).

See: Qlik Management Console

Reload

The reload task is used to fully reload the data in a app from the source. Any old data is discarded.

Sync

Within a multi-node site, one instance of the Qlik Sense Repository Service (QRS) runs on each node. The QRS running on the central node is considered to be the master. The master QRS has direct access to the central repository database, whereas the other QRSs only have access to a local repository database on the node where they are running. The master QRS synchronizes the central repository database and the local repository databases.

The sync task is used to schedule the synchronization of the central repository database and the local repository databases within a multi-node site.
