UUIDs are often used as database table primary keys. They are easy to generate, easy to share between distributed systems and guarantee uniqueness. Here is an article about the topic of the Postgres database. https://lnkd.in/df5SrAw3

In #PostgreSQL, clustered indexes are handled differently than in some other database systems. PostgreSQL allows you to create a clustered index using the CLUSTER command, which physically reorders the table data based on the index. #PostgreSQLPerformance @MinervaDB #dba https://zurl.co/uWS3

🚀 Database Optimization Journey with PostgreSQL 🚀 I recently published two articles on Medium about my experience with optimizing a massive PostgreSQL database to improve performance and reclaim space: 1️⃣ Efficiently Deleting Billions of Records: I tackled the challenge of batch deleting 21 billion rows without downtime. Learn why I chose batch deletion, used raw SQL over ActiveRecord, and how I managed the process seamlessly. https://lnkd.in/eS8bPi_r 2️⃣ Removing Table Bloat for Better Performance: After deletion, bloat remained a problem. My follow-up article explains techniques like VACUUM, autovacuum tuning, and bloat monitoring to keep PostgreSQL tables lean and efficient. https://lnkd.in/e-ErZFz5 #PostgreSQL #DatabaseOptimization #Backend #RubyOnRails #WebDevelopment
