## Валидация данных { #data-validation }

- MinIO also supports expansion of existing clusters in server pools. Each pool is a self contained entity with same SLA's (read/write quorum) for each object as original cluster. By using the existing namespace for lookup validation MinIO ensures conflicting objects are not created. When no such object exists then MinIO simply uses the least used pool to place new objects.

### There are no limits on how many server pools can be combined

### Поле `examples` в JSON Schema { #json-schemas-examples-field }

Позже в новой версии спецификации JSON Schema было добавлено поле <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>.

А затем новый OpenAPI 3.1.0 был основан на последней версии (JSON Schema 2020-12), которая включала это новое поле `examples`.

import static org.junit.jupiter.api.Assertions.assertTrue;

/**

@Deprecated
class DefaultModelValidatorTest {

    private ModelValidator validator;

    private Model read(String pom) throws Exception {
        String resource = "/poms/validation/" + pom;
        try (InputStream is = getClass().getResourceAsStream(resource)) {
            assertNotNull(is, "missing resource: " + resource);

### JSON Schemas Feld `examples` { #json-schemas-examples-field }

Aber dann fügte JSON Schema ein <a href="https://json-schema.org/draft/2019-09/json-schema-validation.html#rfc.section.9.5" class="external-link" target="_blank">`examples`</a>-Feld zu einer neuen Version der Spezifikation hinzu.

Então, com essa declaração de tipo, o **FastAPI** fornece <abbr title="convertendo a string que vem de um request HTTP em dados Python">"parsing"</abbr> automático do request.
