The course does a good job comparing Spark’s distributed processing with traditional ETL tools, so you understand why Spark is used.

Learners feel they actually build powerful pipelines — from raw ingestion to analytics-ready outputs, not just toy examples.

Learners get a solid understanding of transformations, actions, filtering, joins, and aggregations using real code examples.

I would have liked a bit more on advanced Spark SQL optimization techniques, but the foundation was solid.

The emphasis on applied Spark SQL, transformations, and JDBC integration gives you real working skills.

Before this, I knew Spark existed — now I use Spark. I feel confident tackling ETL challenges at work.

Helps build a strong foundation in distributed data processing

I liked how this course didn’t just talk about Spark, but actually showed me how to build and run ETL pipelines — that’s rare in short courses.

At roughly a few hours of content, the course doesn’t overwhelm and is easy to complete in a weekend or short crash-learning session.

Overall a decent starting point, but learners may need additional resources to fully master more advanced Spark features.

The exercises are useful for reinforcing concepts, though deeper optimization topics are limited.

Error handling and data quality considerations are touched upon, adding practical value.

You feel productive quickly because you’re writing working Spark jobs.

Course pace is a bit fast, especially for learners new to Spark concepts.
