return user_id


# A Pydantic model
class User(BaseModel):
    id: int
    name: str
    joined: date

Sau đó có thể được sử dụng:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",
    "joined": "2018-11-30",
}

my_second_user: User = User(**second_user_data)

#### MINIO_ETCD_ENDPOINTS

This is comma separated list of etcd servers that you want to use as the MinIO federation back-end. This should
be same across the federated deployment, i.e. all the MinIO instances within a federated deployment should use same
etcd back-end.

#### MINIO_DOMAIN

This is the top level domain name used for the federated setup. This domain name should ideally resolve to a load-balancer

    #  You can set SchemaSyncCheck settings.
    #  This property is valid when the property 'user' is set.
    #  Elements of this map are as below:
    #   o url: The URL for connecting database. (NotRequired - Default same as databaseInfoMap)
    #   o schema: The schema name. (NotRequired - Default '' e.g. no setting when MySQL)
    #   o user: The database user name. (Required)
    #   o password: The database password. (NotRequired - Default '')

 * (i.e. the <i>main</i> artifact) or the ones that will be used when building <i>tests</i>).
 * <p>
 * This extensible enum has two defined values, {@link #MAIN} and {@link #TEST},
 * but can be extended by registering a {@code org.apache.maven.api.spi.ProjectScopeProvider}.
 * <p>
 * Implementation must have {@code equals()} and {@code hashCode()} implemented, so implementations of this interface
 * can be used as keys.
