During some execution I’ve ended up with a
DataFrame which has a very specific schema I don’t know beforehand. I’d like to export this schema to disk, to be able to use it later.
Export Schema as JSON
json: str = df.schema.json()
Then save it somewhere.
Import Schema from JSON
import json from pyspark.sql.types import StructType json_object = json.loads(json_text) schema = StructType.fromJson(json_object)
Have a question⁉ Contact me.
