ConflictResolutionMode

One of the values of the ConflictResolutionMode enumeration.

ResolutionPath

Gets or sets the path which is present in each item in the Azure Cosmos DB service for last writer wins conflict-resolution. This path must be present in each item and must be an integer value. In case of a conflict occurring on a item, the item with the higher integer value in the specified path will be picked. If the path is unspecified, by default the time stamp path will be used.

public string ResolutionPath { get; set; }

Property Value

string

The path to check values for last-writer wins conflict resolution. That path is a rooted path of the property in the item, such as "/name/first".

Examples

conflictResolutionPolicy.ConflictResolutionPath = "/name/first";
