In lots of cases, a structure for efficient querying results in successful modifications, but you ought to constantly evaluate whether this is the case to your unique situation.

This lessens the volume of writes it must conduct to the blob support. Should you be employing a similar Answer in your individual application, you need to think about how to handle the trade-off amongst reliability (writing every log entry to blob storage because it takes place) and price and scalability (buffering updates as part of your application and creating them to blob storage in batches).
