The YugabyteDB community delivered a free "YSQL Development Intermediate" training and certification class on April 22, 2021. The 90-minute course covered various topics such as YugabyteDB review and setup, constraints, UDFs, expressions, and operators, indexes, views, triggers, extensions, and more. Over 40 exercises were worked through to demonstrate how developers can apply their PostgreSQL knowledge to YugabyteDB. The certification exam was moderately challenging, with an average rating of 3 out of 5, indicating that careful studying is required to pass. The community also addressed several questions from attendees, including migration from IBM DB2, fine-tuning the default sharding strategy, and recovering a dropped database. The next training and certification in the series is scheduled for May 27, with registration available for free.
