Thanks for the information. You can also use Ray packages(Python) for compute intensive tasks, specifically for those tasks which cannot be parallelised in Spark. Example if you performing an Network analysis on a Graph.

Hi Bro, Thanks for this video tutorial. Could you please provide the json file dynamic flattening function explanation as promised in video 13 please.

[sandeepnarwal]

is this same as PySpark Parallel processing? If not how can we use parallel processing in PySpark?

How to add exception handle and stop the loop in above

[uzairmustafa]

Is this multithreading or multi processing? Its a bit unclear

[sreekanth]

As Spark is also a parallel Distributed service can we achieve same without importing those "Multiplrocessing thread pools"?

The title says Azure Databricks, and you are using AWS Community Edition, and the example is not Azure-specific. Databricks is a cloud-agnostic tool.
