### Create Models { #create-models }

Import `SQLModel` and create a database model:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

The `Hero` class is very similar to a Pydantic model (in fact, underneath, it actually *is a Pydantic model*).

There are a few differences:

```java
if (!context.getConfig().isUseLeases() || !session.supports(SMB3_0)) {
    // Fall back to traditional oplock mechanism
    useOplockInstead();
}
```

public class LeaseStatistics {
    private final AtomicLong leasesRequested = new AtomicLong();
    private final AtomicLong leasesGranted = new AtomicLong();

	o = bts

}

// Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (z BatchJobSizeFilter) Msgsize() (s int) {
	s = 1 + 11 + msgp.Int64Size + 11 + msgp.Int64Size
	return
}

// DecodeMsg implements msgp.Decodable
func (z *BatchJobSnowball) DecodeMsg(dc *msgp.Reader) (err error) {

### Crear Modelos

Importa `SQLModel` y crea un modelo de base de datos:

{* ../../docs_src/sql_databases/tutorial001_an_py310.py ln[1:11] hl[7:11] *}

La clase `Hero` es muy similar a un modelo de Pydantic (de hecho, en el fondo, realmente *es un modelo de Pydantic*).

Hay algunas diferencias:

- github.com/envoyproxy/protoc-gen-validate: [v0.9.1 → v1.0.2](https://github.com/envoyproxy/protoc-gen-validate/compare/v0.9.1...v1.0.2)

        }
        
        // Wait for all reconnections
        CompletableFuture.allOf(futures.toArray(new CompletableFuture[0])).join();
    }
}
```
