Architecting FoundationDB's Distributed Transaction Layer: Logs, Sequencers, and Conflict Resolution

FoundationDB’s transaction layer achieves serializable isolation through a carefully orchestrated dance of logs, sequencers, and conflict resolution. This post breaks down the architecture, the role of each component, and how the system guarantees correctness under failure.
