Is it possible to build strongly consistent storage systems on top of eventual? The short answer is “yes”, and the long answer is “yes, but not really, but maybe, but it depends.”

The industry has introduced distributed transactions with async replication to overcome the limits of write performance. However, with distributed transactions and replica reads, the eventual consistency has been introduced as a caveat. In this talk, we will observe an opportunity to build a strongly consistent caching system on top of the eventually consistent Redis Cluster.
