Why "Just Use Postgres" Isn't Always Enough

In this episode of My Weird Prompts, we dive into the "Just Use Postgres" movement and ask a critical question: is the era of specialized databases finally over? While Postgres has become a Swiss Army knife for modern engineering, physical constraints and hardware architecture eventually force a divide between transactional and analytical workloads. We break down the fundamental differences between row-based and columnar storage, explaining why your "Ferrari" database might melt if you try to use it like a "dump truck" for big data. From the power of vectorized execution and SIMD instructions to the complexities of real-time data pipelines using Change Data Capture (CDC) and Apache Kafka, we explore how giants like Netflix manage massive data scales. Whether you are a minimalist developer or a data architect, this deep dive into the internal geometry of databases will change how you think about your tech stack.
