# Clase Join
<a name="aws-glue-api-crawler-pyspark-transforms-join"></a>

Realiza una unión de igualdad en dos `DynamicFrames`.

## Ejemplo
<a name="pyspark-Join-example"></a>

Le recomendamos que utilice el método [`DynamicFrame.join()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-join) para unir a `DynamicFrames`. Para ver un ejemplo de código, consulte [Ejemplo: uso de join para combinar `DynamicFrames`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-join-example).

## \$1\$1call\$1\$1(frame1, frame2, keys1, keys2, transformation\$1ctx = "")
<a name="aws-glue-api-crawler-pyspark-transforms-join-__call__"></a>

Realiza una unión de igualdad en dos `DynamicFrames`.
+ `frame1`: primer `DynamicFrame` que debe unirse (obligatorio).
+ `frame2`: segundo `DynamicFrame` que debe unirse (obligatorio).
+ `keys1`: claves que deben unirse en la primera trama (obligatorio).
+ `keys2`: claves que deben unirse en la segunda trama (obligatorio).
+ `transformation_ctx`: cadena única que se utiliza para identificar la información del estado (opcional).

Devuelve un `DynamicFrame` nuevo que se crea cuando se unen los dos `DynamicFrames`.
