PySpark - Generate StructType from string

Question

Is there a simple way to generate a schema from a structype definition from a string ?

For example I actualy do :

from pyspark.sql.types import *
customSchema = StructType([StructField("Date",StringType(),True)]) 

And i'm looking to store the schema définition in a table and load it dynamically like :

from pyspark.sql.types import *
stringShema = 'StructType([StructField("Date",StringType(),True)])'
customSchema = SomeFunctionToConvertTextToStruct(stringShema)

Any hint ? Regards,

Answer 1

Using eval?

from pyspark.sql.types import *
stringSchema = 'StructType([StructField("Date",StringType(),True)])'
customSchema = eval(stringSchema)
