What does the Server Action 'Sync: ServerDataSync' achieve?

The Server Action 'Sync: ServerDataSync' is responsible for synchronizing data between the local storage of a mobile application and the data stored on the server. This action is crucial in mobile applications where offline functionality is needed. When users interact with the app offline, their changes or additions to the data are typically stored locally. The 'Sync: ServerDataSync' action is what facilitates the merging or updating of this local data with the server data once a connection is re-established. This ensures that both the server and mobile device have the most up-to-date information, thereby maintaining data consistency across platforms.

This action does not simply initialize local storage data, delete data, or create new server-side entities, which are functions of different actions. Initializing local storage refers to setting up an empty state for the data, while deleting local storage data would remove any existing data rather than merge or sync it. Creating new server-side entities pertains to the establishment of new data structures on the server side, which is not the role of the data sync operation.
