Perceba que nesse caso nós estamos usando a função padrão do Python `open()` que interage com um arquivo.

Então, isso envolve I/O (input/output), que exige "esperar" que coisas sejam escritas em disco.

Mas `open()` não usa `async` e `await`.

Então, nós declaramos uma função de manipulação de evento com o padrão `def` ao invés de `async def`.

### SIG Scheduling
[Pod Priority and Preemption](https://kubernetes.io/docs/concepts/configuration/pod-priority-preemption/) has graduated to Beta, so it is enabled by default. Note that this involves [significant and important changes for operators](https://github.com/kubernetes/sig-release/pull/201/files). The team also worked on improved performance and reliability of the scheduler.

### SIG Storage

 * correctly, calls must be chained as illustrated above.

 * <p>Performance note: Even though the {@code ComparisonChain} caller always invokes its {@code
 * compare} methods unconditionally, the {@code ComparisonChain} implementation stops calling its

For "synchronous" (contrary to "asynchronous") they commonly also use the term "sequential", because the computer / program follows all the steps in sequence before switching to a different task, even if those steps involve waiting.

### Concurrency and Burgers { #concurrency-and-burgers }

This idea of **asynchronous** code described above is also sometimes called **"concurrency"**. It is different from **"parallelism"**.
