It could even be an infinite stream, where you keep sending data.

## JSON Lines { #json-lines }

In these cases, it's common to send "**JSON Lines**", which is a format where you send one JSON object per line.

   * Even if no other references to classes from the application class loader remain, the Finalizer
   * thread keeps an indirect strong reference to the queue in ReferenceMap, which keeps the
   * Finalizer running, and as a result, the application class loader can never be reclaimed.
   *
   * This means that dynamically loaded web applications and OSGi bundles can't be unloaded.

    MockReference(FinalizableReferenceQueue frq) {
      super(new Object(), frq);
    }

    @Override
    public void finalizeReferent() {
      finalizeReferentCalled = true;
    }
  }

  /**
   * Keeps a weak reference to the underlying reference queue. When this reference is cleared, we
   * know that the background thread has stopped and released its strong reference.
   */

For example, when you type `python` in the terminal, the operating system looks for a program called `python` in the **first directory** in that list.

If it finds it, then it will **use it**. Otherwise it keeps looking in the **other directories**.

Those two tasks are what **consume time the most**. That's the main work of maintaining FastAPI.

If you can help me with that, **you are helping me maintain FastAPI** and making sure it keeps **advancing faster and better**. 🚀

/// tip

- Do not add trailing punctuation to headings.

### Quotes

- Keep quote style consistent with the existing Korean docs.
- Never change quotes inside inline code, code blocks, URLs, or file paths.

### Ellipsis

- Keep ellipsis style consistent with existing Korean docs (often `...`).
- Never change `...` in code, URLs, or CLI examples.

### Preferred translations / glossary

- If you translate a concept one way, keep it consistent across all occurrences.

### Links and references

- Never modify link syntax like `{.internal-link target=_blank}`.
- Keep markdown link structure intact: `[text](url){.internal-link}`.

### Preferred translations / glossary

Do not translate technical terms like path, route, request, response, query, body, cookie, and header, keep them as is.
