Set default "spark.driver.maxResultSize" from the notebook

Hello,

I would like to set the default "spark.driver.maxResultSize" from the notebook on my cluster. I know I can do that in the cluster settings, but is there a way to set it by code?

I also know how to do it when I start a spark session, but in my case I directly load from the feature store and want to transform my pyspark data frame to pandas.

from databricks import feature_store
import pandas as pd
import pyspark.sql.functions as f
from os.path import join
 
fs = feature_store.FeatureStoreClient()
 
prediction_data = fs.read_table(name=NAME)
 
prediction_data_pd = prediction_data.toPandas()

Hi @Kaniz Fatma​  thanks for your reply.

Not sure if that helps. When I check after execution of your code with

spark.conf.get("spark.driver.maxResultSize")

I still get the default "spark.dirver.maxResultSize", instead of 4096.
