Consider an application with two managed object contexts and a single persistent store coordinator. Alternatively, if the object is standalone, set the merge policy on the context to NSOverwriteMergePolicy. ; Query the ingested data by using Azure Data Explorer. The object itself has been deleted in moc1 but has not changed in moc2. Note how the manager relationship has moved from Lau to Weiss. A federated database system is a type of meta-database management system (DBMS), which transparently maps multiple autonomous database systems into a single federated database.The constituent databases are interconnected via a computer network and may be geographically decentralized. (Constraints, background context, network and JSON decoding) This is a fairly common situation when an application is importing data from a network and the user can also edit that data. An application that fetches hundreds of rows of data can build up a large cache of snapshots. When one of the managed object contexts is saved, its changes are pushed through the persistent store coordinator to the persistent store. Bug Reporter Creating and Modifying Custom Managed Objects, Conflict Detection and Optimistic Locking, NSManagedObjectContextDidSaveNotification, Apple's Unsolicited Idea Submission Policy.
