Optimizing Blob Storage Query Performance

Dennes Torres compares several strategies for querying data stored in Azure Blob Storage:

In the third part of the series Querying Blob Storage with SQL, I will focus on the performance behaviour of queries: What makes them faster, slower, and some syntax beyond the basics.

The performance tests in this article are repeated, and the best time of the queries is recorded. This doesn’t mean you will always achieve the same timing. Many architectural details will affect the timing, such as cache, first execution, and so on. The timing exposed on each query is only a reference pointing to the differences of the query methods that can affect the time and the usual result for better or worse performance.

Click through to see which patterns perform well and which don’t.
