I took this course because I wanted to get up to speed with modern distributed DB tech for a new project at work. The material was spot‑on – especially the chapter on sharding and the practical demo of MongoDB Atlas. I actually used the shard‑key selection guidelines in my own system and saw a 30% performance boost. The videos were clear and the quizzes helped cement the concepts. It was a relaxed yet informative vibe, and I left feeling confident about tackling distributed data challenges.
