CRDTs Explained: Achieving Conflict-Free Synchronization
October 26, 2023
In distributed computing, keeping data consistent across multiple nodes is always a tricky problem. Traditional methods for ensuring consistency, like consensus protocols, often need complex synchronisation that can slow everything down and hurt scalability. Conflict-Free Replicated Data Types (CRDTs) offer an elegant solution by enabling replicas to reach eventual consistency without requiring heavy coordination. CRDTs are designed to be conflict-free, which means replicas can independently modify data and still end up in the same state. This post takes a deep dive into how CRDTs work, including a detailed analysis of common types, with code examples.
