Overview
The knowledge graph service includes a Sync feature which is used when working with knowledge graphs offline. Sync-enabled knowledge graph services allow ArcGIS clients to create local copies of the graph data and data model and sync changes back and forth.
Sync supports multiple editors where each editor can choose to work with a subset of data. For example, an organization can use sync to collect data from workers deployed with mobile devices in the field.
Workflows involving read only clients are also supported. For example, a client can sync to keep a local copy up to date with changes made on the server.
The following service resource operations are provided with sync:
- Create Replica - Sets up a client to run sync. The process creates a replica on the server which is referenced when syncing and the initial replica data file to download.
- Synchronize Replica - Performs the sync.
- Unregister Replica - Unregisters a replica on the server.
- Replicas - Provides a list of all accessible replicas. Additionally, Replica Info provides the replica definition of a specific
replica.Id - Trim Change Log - Allows administrative clients to improve Sync performance by removing change log entries made to a knowledge graph service that fall outside of a specified window of time.
