Теперь это должно звучать понятнее. ✨

Именно это «движет» FastAPI (через Starlette) и обеспечивает столь впечатляющую производительность.

   * <p>When eviction is necessary, the cache evicts entries that are less likely to be used again.
   * For example, the cache may evict an entry because it hasn't been used recently or very often.
   *
   * <p>If {@code maximumSize} is zero, elements will be evicted immediately after being loaded into
   * cache. This can be useful in testing, or to disable caching temporarily.

Isso pode fazer mais sentido agora. ✨

Tudo isso é o que empodera o FastAPI (através do Starlette) e que o faz ter uma performance tão impressionante.

    Castle is great! But it's a large dependency (6.5 MiB) and its security provider feature
    impacts VM-wide behavior.

 *  New: Reduce contention for applications that make a very high number of concurrent requests.
    Previously OkHttp used its connection pool as a lock when making changes to connections and
    calls. With this change each connection is locked independently.

 * **`CertificatePinner` now supports wildcard hostnames.** As always with
   certificate pinning, you must be very careful to avoid [bricking][brick]
   your app. You'll need to pin both the top-level domain and the `*.` domain
   for full coverage.

    ```java
     client.setCertificatePinner(new CertificatePinner.Builder()
