ConflictResolutionPolicy

Examples

A collection with custom conflict resolution with no user-registered stored procedure.

var collectionSpec = new DocumentCollection { Id = "Multi-master collection", ConflictResolutionPolicy policy = new ConflictResolutionPolicy { Mode = ConflictResolutionMode.Custom } }; DocumentCollection collection = await client.CreateDocumentCollectionAsync(databaseLink, collectionSpec });

A collection with custom conflict resolution with a user-registered stored procedure.

var collectionSpec = new DocumentCollection { Id = "Multi-master collection", ConflictResolutionPolicy policy = new ConflictResolutionPolicy { Mode = ConflictResolutionMode.Custom, ConflictResolutionProcedure = "conflictResolutionSprocName" } }; DocumentCollection collection = await client.CreateDocumentCollectionAsync(databaseLink, collectionSpec });

A collection with last writer wins conflict resolution, based on a path in the conflicting documents.

var collectionSpec = new DocumentCollection { Id = "Multi-master collection", ConflictResolutionPolicy policy = new ConflictResolutionPolicy { Mode = ConflictResolutionMode.LastWriterWins, ConflictResolutionPath = "/path/for/conflict/resolution" } }; DocumentCollection collection = await client.CreateDocumentCollectionAsync(databaseLink, collectionSpec });

Constructors

ConflictResolutionPolicy()

Initializes a new instance of the ConflictResolutionPolicy class for the Azure Cosmos DB service.

Properties

ConflictResolutionPath	Gets or sets the path which is present in each document in the Azure Cosmos DB service for last writer wins conflict-resolution. This path must be present in each document and must be an integer value. In case of a conflict occuring on a document, the document with the higher integer value in the specified path will be picked. If the path is unspecified, by default the Timestamp path will be used.
ConflictResolutionProcedure	Gets or sets the StoredProcedure which is used for conflict resolution in the Azure Cosmos DB service. This stored procedure may be created after the DocumentCollection is created and can be changed as required.
Mode	Gets or sets the ConflictResolutionMode in the Azure Cosmos DB service. By default it is LastWriterWins.
