enabled by default. The following configuration settings allow for more staggered delay in terms of usage calculation. The scanner adapts to the system speed and completely pauses when the system is under load. It is possible to adjust the speed of the scanner and thereby the latency of updates being reflected. The delays between each operation of the scanner can be adjusted by the `mc admin config set alias/ delay=15.0`. By default the value is `10.0`. This means the scanner will sleep *10x* the...

# Subdependências

Você pode criar dependências que possuem **subdependências**.

Elas podem ter o nível de **profundidade** que você achar necessário.

O **FastAPI** se encarrega de resolver essas dependências.

## Primeira dependência "injetável"

Você pode criar uma primeira dependência (injetável) dessa forma:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[8:9] *}

    }

    @Test
    @DisplayName("Should limit retry delay to maximum")
    void testMaxDelayLimit() {
        // Given
        SmbOperationException.RetryPolicy policy = new SmbOperationException.RetryPolicy(10, 1000, 5000, 2.0, true);

        // When - Calculate delays for increasing attempts
        long delay1 = policy.getDelayMs(1);
        long delay2 = policy.getDelayMs(2);

Alguns deles também ✨ [**patrocinam o FastAPI**](../help-fastapi.md#sponsor-the-author){.internal-link target=_blank} ✨, isso garante o **desenvolvimento** contínuo e saudável do FastAPI e seu **ecossistema**.

Se você quiser utilizar o nome das funções da sua API como `operationId`s, você pode iterar sobre todos esses nomes e sobrescrever o `operationId` em  cada *operação de rota* utilizando o `APIRoute.name` dela.

Você deve fazer isso depois de adicionar todas as suas *operações de rota*.
