Database Memory and Disk I/O Management - Lecture 6

Explore database memory and disk I/O management in this comprehensive lecture from CMU's Intro to Database Systems course. Delve into key aspects of buffer pool management, including page tables, lock vs. latch mechanisms, and multi-buffer pools. Learn about advanced techniques such as prefetching, scan sharing, and cursor sharing. Understand the intricacies of buffer pull bypass, clock algorithm, sequential flooding, and LRU (Least Recently Used) strategy. Gain insights from Professor Andy Pavlo's expertise as he covers crucial concepts for optimizing database performance and efficiency.
