This article discusses the complexity of maintaining data consistency in distributed environments and introduces conflict-free replicated data types (CRDTs) as a solution for resolving concurrent data changes. It covers strong and eventual consistency, replication conflicts, how Google Docs handles conflicts using operational transformations (OTs), and the advantages and disadvantages of CRDTs.
