带有 ORDER BY 的 Documentdb SDK 导致 ServiceUnavailableException

Question

我正在使用 DocumentDB。给定索引策略：

messageType: 字符串 - 精度 -1

deviceId: 字符串 - 精度 -1

查询 1：

SELECT * FROM c WHERE c._ts >= 1563721200 AND c._ts < 1563807600 AND c.messageType = 'attack' AND c.deviceId >= 'A' AND c.deviceId < 'Z'

查询 2：

SELECT * FROM c WHERE c._ts >= 1563721200 AND c._ts < 1563807600 AND c.messageType = 'attack' AND c.deviceId >= 'A' AND c.deviceId < 'Z' ORDER BY c._ts DESC

执行代码：

var query = dbClientSource.CreateDocumentQuery<Document(UriFactory.CreateDocumentCollectionUri(db, collection),
             sql,
             new FeedOptions { MaxItemCount = 100, EnableCrossPartitionQuery = true })
             .AsDocumentQuery();
while (query.HasMoreResults)
       var result = await query.ExecuteNextAsync<Telemetry>();

查询 1 有效，但查询 2 抛出异常：

{
  "code": "ServiceUnavailable",
  "message": "The request failed because the client was unable to establish connections to 1 endpoints across 1 regions. The client CPU was overloaded during the attempted request.
}

不同的是"ORDER BY"命令。有什么解决办法吗？

Answer 1

我在门户中测试了查询 2，它非常有效。因此，在应用程序中，我将 ConnectionPolicy 更改为：

网关 - Https

现在应用程序正在运行。这个问题看起来与 Document DB SDK 有关，以确保我会继续测试并报告给 Github 存储库。
