Question

我有一个Azure流分析。

输入是我的EventHub。输出是我的带有Mongo API的CosmosDB

通常，如果我从代码中保存了一些东西，那么文档就像这样：

{
"$t" : 3,
"$v" : {
    "_id" : {
        "$t" : 7,
        "$v" : "Z\rSGtþÎ\u0003úL\b"
    },
    "x_right" : {
        "$t" : 1,
        "$v" : 201
    },
    "x_left" : {
        "$t" : 1,
        "$v" : 261
    },
    "time" : {
        "$t" : 2,
        "$v" : "2017-11-16 09:58:42"
    }
},
"id" : "NWEwZDUzNDc3NGZlY2UwM2ZhNGM5OTA4",
"_rid" : "qPdEAK0XVQAEAAAAAAAAAA==",
"_self" : "dbs/qPdEAA==/colls/qPdEAK0XVQA=/docs/qPdEAK0XVQAEAAAAAAAAAA==/",
"_etag" : "\"000047ff-0000-0000-0000-5a0d53470000\"",
"_attachments" : "attachments/",
"_ts" : 1510822727}

但我的Stream-Analytics会像这样保存：

{
"x_left" : 100,
"x_right" : 200,
...}

不同的是“$ t”和“$ v”。

因此我无法从NodeJS中读取mongodb保存的文档并收到此错误：

MongoError: Unknown server error occurred when processing this request.

名称：'MongoError'，消息：'处理此请求时发生未知服务器错误。'

修改来自Streamanalytics的查询：

Select
*
INTO
    proximitycosmosdb
From
    parkingspaceeventhub

proximitycosmosdb是我的带有Mongo-API的CosmosDB parkingspaceeventhub是我的EventHub。

数据将通过JF中的MicrosoftFramework for Java发送到事件中心：

{
"x_left": 100,
"x_right": 100,
"y_right": 2,
}

谢谢！

Azure流分析以不同格式保存数据，而无需“$ t”“$ v”
