How to optimize slow queries with EXPLAIN to fix bad query plans: Make sure to join us for next week's webinar! In this webinar on June 18th, 9:30am PT, you will get an introduction on using EXPLAIN effectively to optimize slow queries in Postgres, and how to identify bad query plans, due to issues such as Postgres planner row mis-estimates. The focus of this webinar is to teach the essential skills of optimizing slow queries with EXPLAIN ANALYZE, teach you about anti-patterns that you will encounter when debugging queries, and leave you with practical advice on how to address common problems.

The 3rd edition of the newsletter is out. 🚀 This time I've taken a stab at the popular topic - CAP theorem In this edition of the newsletter, I've discussed: 1. CAP theorem: Statement 2. Consistency or Availability? 3. Problems with CAP theorem for Distributed systems 4. Conclusion Sneak peak: Problem 1: CAP-consistency (Linearizability) comes at a cost and most systems don’t want that. When you chose linearizability, it means your system is okay to pay the performance penalty i.e. not process reads and writes unless all database nodes are in sync. But, is that the need for most of our systems today? Well, not really. Consider the case of social media platforms, we all know more than hundreds of million users are active daily. It’s completely okay to give up consistency and show posts by a slight delay rather than to give up the availability. In true sense, availability in today’s world is tied to your revenue. You might be able to manage consistency using some algorithms but low availability directly means losing business. _______ Subscribe to get weekly stab at technical concepts in future.

🧠📊 Just dove into revising this foundational topic and delved deep into the world of linked lists. 📝🔗 Explored types of linked lists, understanding their differences and use cases.💡 Can't wait to continue expanding my knowledge and applying these concepts in real-world scenarios. There are several types of linked lists. Some common ones include: 1.💎Singly Linked List:** Each node contains data and a reference to the next node in the sequence. 2.💎Doubly Linked List:** Each node contains data and references to both the next and previous nodes. 3.💎Circular Linked List:** Similar to a singly or doubly linked list, but the last node's reference points back to the first node in a circular manner. 4.💎Singly Linked List with a Tail Pointer:** A variation of the singly linked list where there's a direct reference to the last node, making appending faster. 5.💎Doubly Linked List with a Tail Pointer:** Similar to the previous type but with references to both the first and last nodes. 6.💎Skip List:** A data structure that uses multiple layers of linked lists to provide efficient search times for sorted data. Each type of linked list has its own advantages and use cases. 🚀 #DataStructures #LearningJourney #LinkedLists #TypeOfLinkedList #cdac

You can now receive reports for each completed bucket scan. To enable the new capability, update the scheduled bucket scan CloudFormation stack(s) as described here: https://lnkd.in/edJv73W4 And set the ReportingAddOnStackName parameter to the stack name of the reporting add-on (if you followed the docs, the name is bucketav-reporting). That's it :)
