Distributed Transactional Database Systems - Lecture 22

Explore distributed transactional database systems in this comprehensive lecture from CMU's Intro to Database Systems course. Delve into topics such as distributed coordinators, two-phase commit protocols, Byzantine fault tolerance, and Paxos consensus algorithm. Learn about early prepare voting, commit requests, replicas, case safety, and replication charts. Examine message tracking, proposals, leader election, and MultiPax. Understand the concepts of heartbeat mechanisms, multi-primary configurations, and primary replica roles in distributed database environments. Gain valuable insights from Professor Andy Pavlo's expertise in this in-depth exploration of distributed OLTP systems.
