Developing PySpark Applications Best Practices ✅ How To Structure Your PySpark Jobs and Code
Developing production suitable PySpark applications is very similar to normal Python applications or packages. It’s quite similar to writing command-line apps, you simply execute the script against the cluster.
00:00 Writing Spark Applications with Python
01:04 PySpark App example
02:04 Create a virtual environment with Pipenv in the same project directory
03:29 Install PySpark
04:08 How to distribute files to the cluster together with the application
05:48 Passing the SparkSession at runtime
07:12 Using spark-submit to run the app
08:02 Summary
08:52 Thank you
To facilitate code reuse, it's common to package multiple Python files into zip files and to include those files, you can use the --py-files argument of spark-submit to add .py, .zip, or .egg files to be distributed with your application. I prefer .zip files but you have options.
When it’s time to run your Spark code, you specify a certain script as an executable script that builds the SparkSession. This is the one that we will pass as the main argument to spark-submit, together with any arguments needed.
