Data Wrangler, a notebook-based tool for exploratory data analysis, now supports both Spark DataFrames and pandas DataFrames, generating PySpark code in addition to Python code. For a general overview of Data Wrangler, which covers how to explore and transform pandas DataFrames, see the the ...
Add some code to the notebook. Use PySpark to read the JSON file from ADLS Gen2, perform the necessary summarization operations (for example, group by a field and calculate the sum of another field) and write the summarized data back to ADLS Gen2. He...

In our newly created Notebook, we will go ahead andload our dataset using pyspark as provided in the Azure Open Datasets. Using the code, we read the data from Azure blob storage as a parquet file, then load the first ten rows of our dataset as follows: ...
Note that the column names used (shown here as user_id, user_name and user_age) need to be updated for each dataset, but the structure will be the same. I also asked CoPilot to translate this SQL code to PySpark and it suggested the code below (with a...
