Data Engineering Learning Journey
This online course is perfect for
Data and Machine Learning Engineers who deal with transformation of large volumes of data and need production-quality code.
Expert Data Scientists can also participate: they will learn how to get the most performance out of Spark and how simple tweaks can increase the performance dramatically.
What will you learn during Optimizing Apache Spark & Tuning Best Practices?
After this training, you will have learned how Apache Spark works internally, the best practices to write performant code, and have acquired essential skills necessary to debug and tweak your Spark applications.
Structured, to-the-point, good combination of theory and practical examples, very knowledgeable trainer who can explain concepts very well
It was a hands-on and tangible course. We could apply what we learned in a matter of minutes. The trainer did a great job of answering ad-hoc questions that complemented the material. We appreciated the fact that we could apply what we were taught directly to our company.
I liked every aspect of this training and would like to thank the trainers. They did an excellent job of explaining how to use Spark for data science. This is the fourth GoDataDriven training I’ve followed. All were great, but this was the best one so far.
Climbing a steep Python and Machine Learning curve in three days. This would have taken me months on my own.
