What is Streaming Used For?

Overview

Why would you need to use streaming? The more specific question is, why would you use streaming in SignalR? After all, it’s not gRPC, where streaming is perhaps the only way to deal with live processed collections. In SignalR, you can send an item of such a collection as soon as it becomes available. You already have a persistent connection open. Well, there are many real-life scenarios where streaming would still be useful, even in SignalR.

If you had to wait for the download to finish, you would have spent a long time waiting before you were able to watch a movie. High-quality movies are gigabytes in size. So, even with a fast internet connection, downloading would still take a noticeable amount of time.
