Raw Azure StreamAnalytics output using Azure Storage

StreamAnalytics is a monster. It is capable of making decisions on large amounts of data, coming in like a stream. It has input sources and output sinks. And in between, a query is running. This query has an SQL-like structure, something like Select * into [output sink] from [input source].

Because I work a lot with the IoT part of Azure (IoT Hubs, EventHubs, etc.), a StreamAnalytics job is a great addition, handling the continuous stream of telemetry, coming from multiple devices.

StreamAnalytics is less known for usage in a non-Internet of Things environment. You can think of handling credit card payments or mutations in personal files.

In my opinion, StreamAnalytics has one drawback; it takes some time to start up and it can only be changed (alter the query of change sinks or sources) when it is stopped again. My biggest issue is that I can not directly see what telemetry is passed.

But there is a simple solution. A query can output the same telemetry (to be more specific, the data you want to pass to the output sink) to multiple sinks. So if you are not sure which data is passed, you can output it to a second sink.

In this blog, I show you how to output to Azure storage sinks. Doorgaan met het lezen van “Raw Azure StreamAnalytics output using Azure Storage”
