This month Gyan Aggarwal will present a talk on the paper “Pure Operation-Based Replicated Data Types” by Carlos Baquero, Paulo Sergio Almeida and Ali Shokar.

Paper abstract: Distributed systems designed to serve clients across the world often make use of geo-replication to attain low latency and high availability. Conflict-free Replicated Data Types (CRDTs) allow the design of predictable multi-master replication and support eventual consistency of replicas that are allowed to transiently diverge. CRDTs come in two flavors: state-based, where a state is changed locally, shipped and merged into other replicas; operation-based, where operations are issued locally and reliably causal broadcast to all other replicas. However, standard definition of op-based CRDT is very encompassing, allowing even sending the full-state, and thus imposing storage and dissemination overheads as well as blurring the distinction from state-based CRDTs. Pure Operation-Based CRTDs send only operations to other replicas, drawing a clear distinction from state-based CRDTs.
