Cosmos DB findOneAndUpdate:对多个参数排序失败，出现意外错误

Question

< li >我已经设置了一个Azure Cosmos DB，它公开了MongoDB API。 < li >我使用mongo shell连接到数据库。 < li >我用< code >使用html" target="_blank">示例创建了一个新的db 示例。 < li >我使用< code > db . sample . insert({ }) 创建了一个简单的集合< code>sample < li >然后，我尝试运行以下查询:

db.sample.findOneAndUpdate({ foo: {"$eq":1}},{ "$set": { "bar":1}},{"sort": { "foo": 1, "bar": 1 }})

当我对一个普通的MongoDB 3.2.0实例运行时，查询成功完成(匹配0个结果)。但是，在CosmosDB上，会生成以下stacktrace:

CosmosDB中是否存在一些普通MongoDB实例中不存在的额外查询限制？这只是CosmosDB的bug吗？报告这类错误的恰当方式是什么？

Answer 1

你没有看到虫子；目前，Cosmos DB的MongoDB API不支持复合索引。您的＜code＞findOneAndUpdate（）的情况下查找，或者使用单个属性＜code＞sort。
