Introduction Monotonic reads is a crucial consistency model in distributed systems that every senior engineer should thoroughly understand, especially when preparing for technical interviews at leading tech companies. This concept…
When designing distributed systems, engineers face crucial decisions about data consistency, system availability, and handling network failures. The CAP theorem, introduced by Eric Brewer in 2000, helps us understand these…
