Efficient synchronisation of state-based CRDTs
Efficient synchronisation of state-based CRDTs Enes et al., arXiv’18 CRDTs are a great example of consistency as logical monotonicity. They come in two main variations: operation-based CRDTs send operations to remote replicas using a reliable dissemination layer with exactly-once causal delivery. (If operations are idempotent then at-least-once is ok too). state-based CRDTs exchange information about…

Applied Monotonicity: A Brief History of CRDTs in Riak
"Our work is inspired by a problem we observed in LVars (Kuper and Newton 2013), Lasp, and BloomL: functions must be monotonic (or homomorphic, a special case of monotonicity) to ensure both correctness and convergence of the system; in each of these systems functions are assumed to be correctly implemented and annotated accordingly. As we demonstrated in this article, *this is very difficult to get right*. Not only is monotonicity difficult to get right in practice, for systems that use monotonicity, they must be high-performance and cheap. In the case of CRDTs, the Observed-Remove Set was much too expensive to actually use in practice, but it’s easy to implement and reason about. For any monotonic solution to gain adoption, it essential that the solutions be both easy to use and not prohibitively expensive."

Solving Flight Monitoring with CRDTs | Freebird
At Freebird, we take flight status monitoring seriously because it can be the difference between snagging a last-minute flight home and sitting in the airport for hours. To make our product work, we need a system that can reason about the world given multiple potentially conflicting views of reality.

To solve this, we used CRDTs, a relatively new concept from distributed systems inspired by modern abstract algebra. CRDTs let us use our air travel domain knowledge to elegantly combine conflicting information from multiple status providers into a single cohesive view. Not only do CRDTs provide a straightforward framework for developing application logic, but simple CRDTs can be effortlessly composed into more powerful CRDTs. Beyond satisfying our basic requirements, CRDTs lend themselves well to extensions such as SQL analytics.
