Week 43 – Intermediate

Because we’re so excited about Python worksheets, Snowpark and all that jazz and because we just love giving you those pesky JSON parsing exercises – this week, we’ve combined the two!

Your job is to create a stored procedure using Python worksheets to parse out the data and make it look like this:

A shameless plug, but if you need a little help, I do cover JSON parsing using Snowpark in the below video:

    Thanks for the challenge. Still getting used to this. Finding the feedback cycle different with the worksheets

    This is the kind of challenge I like! I had some fun with this one, challenging myself to do it without converting the Snowflake dataframe to a Pandas one.

    From my understanding, converting the Snowflake dataframe into a pandas one will execute the SQL in Snowflake to retrieve the Snowflake dataframe, then store the whole thing in memory whilst you work with it using the pandas dataframe. As I have avoided using pandas, my procedure runs as if it is executing a single SQL command.

    This doesn’t really mean much when you are running the procedure inside Snowflake as a Python worksheet, but I would expect my non-pandas solution to have much better performance when executing on a local machine, as the work will be pushed down to Snowflake instead of executed locally

    Nice way to learn more about snowpark and manipulating data with python
