This lecture covers the principles of the Two-Phase Commit (2PC) protocol, detailing the process of prepare, vote, commit/abort, and acknowledgment messages. It also discusses scenarios like coordinator and subordinate failures, site and link failures, and the use of presumed commit/abort. Additionally, it explores replication strategies such as synchronous and asynchronous replication, primary site replication, and peer-to-peer replication. The lecture delves into the CAP theorem, consistency, availability, and partition tolerance, as well as the transition from ACID to BASE properties in NoSQL systems.
