CCA 175 "Perform standard extract, transform, load (ETL) processes on data"?

Hi Durga,
I am going through the new syllabus for CCA-175. Under “Transform, Stage, and Store” section, they have included “Perform standard extract, transform, load (ETL) processes on data”. Can you please explain what comes under this section? Please provide references to the videos if it is already covered in the itversity playlist. Thank You

It is about Core Spark API - Transformations and Actions.

Start following this playlist as per revised syllabus

Thank you Durga for the details.
