我正在路径https://github.com/Azure/azure-documentdb-dotnet/tree/master/samples/ChangeFeedMigrationTool中运行Change Feed Processor示例 . 我只更改了App.config文件中所需的键值以指向我的Cosmos DB .
当我针对分区集合运行此示例时，我在注册观察者工厂时遇到异常 .
await host.RegisterObserverFactoryAsync(docObserverFactory);
例外细节：
InvalidOperationException: PartitionKey value must be supplied for this operation.

但该函数不接受任何分区键 . 而且我不知道如何通过一个 . 我错过了什么吗？另外，我的理解是Cosmos DB Change Feed Processor库隐式管理所有分区 .

租赁集合是否已分区？目前不支持分区租约集合（应该很快），并且错误消息将是这样的 . 您可以尝试使用单分区租约收集 .
