Question

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);

例外情况：

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

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

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。

租约收集是否已分区？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。

如何在Cosmos DB Change Feed处理器中为RegisterObserverFactoryAsync函数提供PartitionKey？
