Beyond the CAP Theorem - Consistency Without Consensus With CRDTs
Explore the world of distributed systems and learn about Commutative and Convergent Replicated Data Types (CRDTs) in this 41-minute conference talk from Devoxx. Dive into the trade-offs involved in building distributed systems, focusing on the balance between availability and strong consistency as outlined in the CAP Theorem. Discover how CRDTs provide strong eventual consistency without requiring complex consensus protocols like Paxos, RAFT, or Zookeeper. Examine the internal structure of CRDTs and how they enable safe concurrent and distributed updates without information loss. Cover topics such as distributed computing, data consistency, dynamic systems, semantic resolution, vector clocks, and practical applications of CRDTs in real-world scenarios like Cassandra and SoundCloud. Gain insights into advanced concepts like CQRS and garbage collection in distributed systems.
