Dataframe pyspark to dict

Question

I have this dataframe path_df:

path_df.show()
+---------------+-------------+----+
|FromComponentID|ToComponentID|Cost|
+---------------+-------------+----+
         


        

Answer 1

Easiest way I know is the below (but has Pandas dependency):

path_df.toPandas().set_index('FromComponentID').T.to_dict('list')
