Lamport Timestamps
Lamport Timestamps are a logical clock algorithm used in distributed systems to order events without relying on synchronized physical clocks. Developed by Leslie Lamport in 1978, they assign monotonically increasing integer timestamps to events based on causal relationships, ensuring a partial order that respects causality. This method helps resolve conflicts and maintain consistency in systems where events occur across multiple processes or nodes.
Developers should learn Lamport Timestamps when working on distributed systems, such as databases, messaging queues, or consensus algorithms, to handle event ordering and detect concurrency issues. They are particularly useful in scenarios requiring causal consistency, like version control systems (e.g., Git) or distributed databases, where understanding the sequence of operations is critical for correctness and conflict resolution.
