## What is a Stream? { #what-is-a-stream }

"**Streaming**" data means that your app will start sending data items to the client without waiting for the entire sequence of items to be ready.

So, it will send the first item, the client will receive and start processing it, and you might still be producing the next item.

```mermaid
sequenceDiagram
    participant App
    participant Client

            super(new java.io.ByteArrayInputStream(new byte[0]), java.nio.charset.StandardCharsets.UTF_8, 1000, null);
            this.output = output;
        }

        @Override
        public void start() {
            // Override start to do nothing in test - simulate immediate completion
        }

        @Override
        public void run() {
            // Override run to do nothing in test
        }

`Depends()` receives a `scope` parameter that can be:

* `"function"`: start the dependency before the *path operation function* that handles the request, end the dependency after the *path operation function* ends, but **before** the response is sent back to the client. So, the dependency function will be executed **around** the *path operation **function***.
