Bending CAP Theorem in Geo-Distributed Deployments With CRDTs
12 years after the original CAP theorem, Eric Brewer wrote a great article on how the rules have changed on CAP. The summary is that using CRDTs (conflict-free replicated data types), one can create a new balance between C, A, and P — commonly referred to as strong eventual consistency.
I will provide a more practical guide here to why CRDTs are great for applications and how CRDT implementation in Redis to provide simplified development for applications running across multiple datacenters.
