Last week I took some break and went for 4 days to Dunkirk and Lille. Very beautiful cities where Spark and Scala are present almost at every step - the proof in the images below :)
Regarding the posts, last week I published 2 pretty global articles about data engineering. The former was about horizontal scalability. If you need some "back to the basics", I can invite you to read Introduction to horizontal scalability. It's the first time when I tried to make the images by hand. I'm curious to see what do you think about it.
I also have 2 new Scala tips (if you see the picture from the beginning, you will understand why ;)) for you on Newsletter 14.04.2019 Scala tips. You will learn how to generate tuples from a sequence and how to apply different transformation logic on the last element of a sequence.
