如何在Cosmos DB Change Feed處理器中為RegisterObserverFactoryAsync函數提供PartitionKey？

Question

我正在路徑https://github.com/Azure/azure-documentdb-dotnet/tree/master/samples/ChangeFeedMigrationTool中運行Change Feed Processor示例。 我只更改了App.config文件中所需的鍵值以指向我的Cosmos DB。

當我針對分區集合運行此示例時，我在注冊觀察者工廠時遇到異常。

await host.RegisterObserverFactoryAsync(docObserverFactory);

例外細節：

InvalidOperationException: PartitionKey value must be supplied for this operation.

   at Microsoft.Azure.Documents.Client.DocumentClient.<AddPartitionKeyInformationAsync>d__34f.MoveNext()
--- End of stack trace from previous location where exception was thrown ---

at ChangeFeedMigrationSample.Program.<RunChangeFeedHostAsync>d__18.MoveNext() in D:\temp\samples\code-samples\ChangeFeedProcessor\Program.cs:line 181
--- End of stack trace from previous location where exception was thrown ---

   at System.Runtime.CompilerServices.TaskAwaiter.GetResult()
   at ChangeFeedMigrationSample.Program.<MainAsync>d__16.MoveNext() in D:\temp\samples\code-samples\ChangeFeedProcessor\Program.cs:line 92

但該函數不接受任何分區鍵。 而且我不知道如何通過一個。 我錯過了什么嗎？ 另外，我的理解是Cosmos DB Change Feed Processor庫隱式管理所有分區。

租賃集合是否已分區？ 目前不支持分區租約集合（應該很快），並且錯誤消息將是這樣的。 您可以嘗試使用單分區租約收集。
