# Concurrency and async / await

Details about the `async def` syntax for *path operation functions* and some background about asynchronous code, concurrency, and parallelism.

## In a hurry?

<abbr title="too long; didn't read"><strong>TL;DR:</strong></abbr>

If you are using third party libraries that tell you to call them with `await`, like:

```Python
results = await some_library()
```

        "DirectoryProperty"           | "objects.directoryProperty()"         | "file('abc')"        | new File('abc')
        "DirectoryProperty"           | "objects.directoryProperty()"         | "null"               | "null"
        "RegularFileProperty"         | "objects.fileProperty()"              | "file('abc')"        | new File('abc')

* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)

## Alternative (old) `Query` as the default value

Previous versions of FastAPI (before <abbr title="before 2023-03">0.95.0</abbr>) required you to use `Query` as the default value of your parameter, instead of putting it in `Annotated`, there's a high chance that you will see code using it around, so I'll explain it to you.
