I've just completed "Data Storage and Queries," the 3rd course in the Coursera Data Engineering Specialization (only one course to go!) This course was a bit of a mixed bag for me. I found it interesting to learn about concepts related to data storage, including: Storage options Query processing Data Lakes Data Lakehouses I also enjoyed the hands-on experience with: Comparing row vs column-based storage with Amazon Redshift and PostgreSQL Graph databases Vector databases Building a Data Lakehouse with AWS Lake Formation and Apache Iceberg. However, I found the advanced SQL section a bit dull, as I use those skills daily. Additionally, I felt the sections on querying streaming data (and using Amazon Managed Service for Apache Flink) would have been more beneficial if we were working with live data instead of static JSON files. Despite these points, I still found the course worthwhile, and I'm looking forward to the next one!

I've just finished the whole program on Data Engineering and found it great! Awesome contents, pace, communication, conversations with guests, and just about the right level of "Challenge" for me. I had lots of fun and learned a lot!
