我们目前正在通过 Azure 流分析将数据从 Azure 事件中心流式传输到 Cosmos DB。我希望能够以编程方式更改在数据流式传输时完成的查询(/转换)。
var existingQuery = AnalyticsClient.Transformations.Get(handler.ResourceGroup, handler.JobName, handler.JobName);
if (job.JobState == "Started")
{
AnalyticsClient.StreamingJobs.BeginStopAsync(handler.ResourceGroup, handler.JobName).Wait();
}
var transformation = new Transformation()
{
Query = $@"SELECT
[key] as partition_key
INTO[{outputName}]
FROM Input",
StreamingUnits = 1
};
AnalyticsClient.Transformations.CreateOrReplace(transformation, handler.ResourceGroup, handler.JobName, handler.JobName);
Stream Analytics Job Properties - 转换显示为空。
尚不清楚转换的默认名称可能是什么,但尝试从作业中获取转换(与作业同名):
{
"code": "NotFound",
"message": "StreamAnalytics_Prototype_2 does not exist in Stream Analytics job 'StreamAnalytics_Prototype_2' in resource group 'removed' in subscription 'removed'.",
"details": {
"code": "404",
"message": "StreamAnalytics_Prototype_2 does not exist in Stream Analytics job 'StreamAnalytics_Prototype_2' in resource group 'removed' in subscription 'removed'.",
"correlationId": "removed",
"requestId": "removed"
}
}
尝试创建转换:
{
"code": "BadRequest",
"message": "The number of transformations defined for this job exceeds the maximum limit of 1 that is supported.",
"details": {
"code": "400",
"message": "The number of transformations defined for this job exceeds the maximum limit of 1 that is supported."
}
}
最佳答案
如果从 Azure 门户创建转换,则转换的默认名称为“Transformation”。如果您从 SDK 创建转换,则需要在代码中指定名称。
streamAnalyticsManagementClient.Transformations.CreateOrReplace(transformation, resourceGroupName, streamingJobName, transformationName);
顺便说一句,在从 Azure 门户添加查询后,我从事件日志中找到了默认转换名称。
关于Azure 流分析 CreateOrReplace 转换冲突或错误请求,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/45171610/
