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

Executa uma junção de igualdade em dois `DynamicFrames`.

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

Recomendamos usar o método [`DynamicFrame.join()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-join) para juntar `DynamicFrames`. Para visualizar um código de exemplo, consulte [Exemplo: usar join para combinar `DynamicFrames`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#pyspark-join-example).

## \_\_call\_\_(frame1, frame2, keys1, keys2, transformation\_ctx = "")
<a name="aws-glue-api-crawler-pyspark-transforms-join-__call__"></a>

Executa uma junção de igualdade em dois `DynamicFrames`.
+ `frame1` – O primeiro `DynamicFrame` da junção (obrigatório).
+ `frame2` – O segundo `DynamicFrame` da junção (obrigatório).
+ `keys1` – As chaves para junção do primeiro quadro (obrigatório).
+ `keys2` – As chaves para junção do segundo quadro (obrigatório).
+ `transformation_ctx` – Uma string única que é usada para identificar informações de estado (opcional).

Retorna um novo `DynamicFrame`, que é criado juntando os dois `DynamicFrames`.
