Reviews summary

Postgresql performance tuning & index mastery

According to learners, this course is a highly practical and invaluable resource for anyone looking to optimize PostgreSQL database performance. Students consistently highlight the clear and concise explanations of the EXPLAIN keyword and query plan analysis, noting its immediate applicability. The course provides a deep dive into various index types and their effective use, making it particularly beneficial for DBAs and backend developers managing production databases. While some experienced users wished for more complex, large-scale examples and a few found the pace challenging for those new to advanced SQL, the overall consensus is that the course delivers actionable insights and significant performance improvements.

Directly applicable techniques for real-world scenarios.

"...provides practical examples that you can immediately apply."

"The tips for populating large datasets were super useful."

"Very practical and straight to the point. I immediately applied some of the EXPLAIN tips and saw improvements."

"I gained practical tools and strategies that I could apply immediately to my work."

Comprehensive insights into PostgreSQL indexing concepts.

"I especially appreciated the deep dive into various index types and when to use them."

"This course really sharpened my understanding of how indexes work internally."

"The explanations of B-tree, GIN, and GiST indexes were clear, and the practical examples showcased their benefits."

"The index discussions were well-structured and easy to follow."

Exceptional clarity on using EXPLAIN for query optimization.

"The instructor explains complex concepts like the EXPLAIN analyze output very clearly and provides practical examples that you can immediately apply."

"It covered the EXPLAIN keyword thoroughly and helped me understand query plans much better."

"This course really sharpened my understanding of how to effectively use EXPLAIN to diagnose performance issues."

"I immediately applied some of the EXPLAIN tips and saw improvements."

Fast-paced, requiring prior advanced SQL familiarity.

"I found the pace a bit fast, especially if you're not already very familiar with advanced SQL concepts."

"Some demos were quick and hard to follow without pausing frequently."

"It assumes you know basic SQL, which is fair."

Could benefit from more complex, large-scale examples.

"I was looking for more in-depth, advanced optimization techniques. While the course covers the basics well, it felt like it only scratched the surface for someone with a few years of experience."

"I felt some parts, especially on advanced indexing strategies, could have had more real-world, larger-scale examples."

"The 'best practices to populate large databases' part felt a bit rushed and could benefit from more detailed scenarios and solutions for common pitfalls."
