## Usar `async` o no usar `async`

Como las dependencias también serán llamadas por **FastAPI** (lo mismo que tus *path operation functions*), las mismas reglas aplican al definir tus funciones.

Puedes usar `async def` o `def` normal.

    /**
     * Add a pending operation

    public void addPendingOperation(CommonServerMessageBlock operation) {
        pendingOperations.add(operation);

     * @param operation operation to remove
     * @return true if operation was removed

## Dependencies for groups of *path operations* { #dependencies-for-groups-of-path-operations }

- [Deploy a Tenant from the MinIO Operator](https://docs.min.io/community/minio-object-store/operations/deployments/k8s-deploy-minio-tenant-on-kubernetes.html)

Install Distributed MinIO on Linux:

And we can add a list of `dependencies` that will be added to all the *path operations* in the router and will be executed/solved for each request made to them.

    /**

     */
    public long getRdmaReads() {
        return rdmaReads.get();
    }

    /**

     *
     * @return write operation count

    public long getRdmaWrites() {
        return rdmaWrites.get();

        @Test
        @DisplayName("delete operation should work correctly")
        void testDelete() throws CIFSException {
            // When/Then
            assertDoesNotThrow(() -> mockResource.delete(), "Delete operation should not throw exception");
            verify(mockResource).delete();
        }

        @Test
        @DisplayName("copy operation should work correctly")

Similar a como puedes [agregar `dependencies` a los *path operation decorators*](dependencies-in-path-operation-decorators.md){.internal-link target=_blank}, puedes agregarlos a la aplicación de `FastAPI`.

En ese caso, se aplicarán a todas las *path operations* en la aplicación:

{* ../../docs_src/dependencies/tutorial012_an_py39.py hl[16] *}

//              below).
//  opers - Array of operations to become the body of the function or null.
//          - If no array is given (`num_opers` = -1), all the
//          operations in `fn_body` will become part of the function
//          except operations referenced in `inputs`. These operations
//          must have a single output (these operations are typically

```

...that's because the client generator uses the OpenAPI internal **operation ID** for each *path operation*.

OpenAPI requires that each operation ID is unique across all the *path operations*, so FastAPI uses the **function name**, the **path**, and the **HTTP method/operation** to generate that operation ID, because that way it can make sure that the operation IDs are unique.

But I'll show you how to improve that next. 🤓
