In the fourth episode of the System Design Weekly Podcast, we explore one of the foundational algorithms in distributed systems: the Two-Phase Commit (2PC)!
Designed to ensure consistency across distributed databases, 2PC is a coordination protocol that helps multiple systems agree on a transaction's outcome—even in the face of network failures or crashes.
In this episode, we break down why 2PC is necessary, how it works step by step, and the trade-offs that come with using it. We also take a look at how technologies like ZooKeeper are commonly used to implement 2PC in real-world systems.
As one of the more approachable distributed algorithms, Two-Phase Commit is a great entry point for engineers beginning their journey into the world of distributed systems.
Tune in and get a clearer understanding of consistency, coordination, and the challenges of building reliable distributed software.
