Azure blob storage and stream analytics

Question

I read what in azure blob very nice save some data for statistics or something else, after it create requests for blob and show statistics to website (dashboard). But I don't know how to use stream analytics for showing statistics. It is some SDK for create query to blob and generate josn data. Or ... I don't know. And I have more question about it:

• How to save data to blob (it is json data or something else). I don't know format data for it issue.
• How to use stream analytics for create request to blob and after it get data for showing in dashboard.

And maybe you know how to use this technology. Help me please. Thanks, and have a nice day.

@Taras - did you get a chance to toy with the Stream Analytics UI?

When you add a blob input you can either add an entire container - which means Stream Analytics will scan the entire container for new files or you can specify a path prefix pattern which will make Stream Analytics look in only that path.

You can also specify tokens such as {date}, {time} on the path prefix pattern to help guide Stream Analytics on the files to read.

Generally speaking - it is highly recommended to use Event Hub as input for the improved latency.

As for output - you can either use Power BI which would give you an interactive dashboard or you can output to some storage (blob, table, SQL, etc...) and build a dashboard on top of that.

You can also try to do one of the walkthroughs to get a feel for Stream Analytics: https://azure.microsoft.com/en-us/documentation/articles/stream-analytics-twitter-sentiment-analysis-trends/
