Transitioning from ContentSync to SmartSync transitioning-from-contentsync-to-smartsync
This section provides an overview to SmartSync feature and how it minimizes server load/storage and network traffic to reduce cost.
Overview overview
SmartSync is the latest mechanism used by AEM Screens. It serves as a replacement of the current method used to cache offline channels and delivering them to the player.
It executes both on the server-side and client-side.
On Server-side:
- Contents of the channels, including assets, are cached in
/var/contentsync. - Cache is exposed to the players via a manifest which describes the available content for a display.
On Client-side:
- Player updates its content based on the manifest generated above.
Benefits of Using SmartSync benefits-of-using-smartsync
SmartSync feature provides several benefits to your AEM Screens project such as the following:
- Dramatic reduction of network traffic and server-side storage requirements.
- Player intelligently downloads assets only if the asset is missing or changed.
- Server-side and client-side storage optimizations.
