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

Esegue un equi join su due `DynamicFrames`.

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

Ti consigliamo di utilizzare il metodo [`DynamicFrame.join()`](aws-glue-api-crawler-pyspark-extensions-dynamic-frame.md#aws-glue-api-crawler-pyspark-extensions-dynamic-frame-join) per unire `DynamicFrames`. Per visualizzare un esempio di codice, consulta [Esempio: usa join per combinare `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>

Esegue un equi join su due `DynamicFrames`.
+ `frame1`: il primo `DynamicFrame` da unire (obbligatorio).
+ `frame2`: il secondo `DynamicFrame` da unire (obbligatorio).
+ `keys1`: le chiavi da unire per il primo frame (obbligatorio).
+ `keys2`: le chiavi da unire per il secondo frame (obbligatorio).
+ `transformation_ctx`: una stringa univoca utilizzata per identificare informazioni sullo stato (opzionale).

Restituisce un nuovo `DynamicFrame` che viene creato unendo i due `DynamicFrames`.
