* @deprecated This method originally used internal JDK APIs (sun.misc.SharedSecrets) for
     *             performance optimization, but those APIs have been removed for safety and
     *             compatibility with modern Java versions. This method now simply calls
     *             {@code new String(chars)}, providing no additional value.
     *             Use the {@link String#String(char[])} constructor directly instead.

       * My impression is that an AtomicReferenceFieldUpdater in a static field is similarly fast to
       * Unsafe on modern JVMs (if perhaps not quite as fast as VarHandle?). However, I'm not sure

MySQL ve PostgreSQL gibi ilişkisel veritabanlarıyla nispeten sıkı bir şekilde bağlantılıdır. Bu nedenle Couchbase, MongoDB ve Cassandra gibi NoSQL veritabanlarını ana veritabanı motoru olarak kullanmak pek de kolay değil.

### Crear el objeto `Settings` { #create-the-settings-object }

Importa `BaseSettings` de Pydantic y crea una sub-clase, muy similar a un modelo de Pydantic.

De la misma forma que con los modelos de Pydantic, declaras atributos de clase con anotaciones de tipos, y posiblemente, valores por defecto.

Importe `BaseSettings` do Pydantic e crie uma subclasse, muito parecido com um modelo do Pydantic.

Da mesma forma que com modelos do Pydantic, você declara atributos de classe com anotações de tipo e, possivelmente, valores padrão.

 * ### Plus a modern API

 * The URL (JDK1.0) and URI (Java 1.4) classes predate builders and instead use telescoping
 * constructors. For example, there's no API to compose a URI with a custom port without also
