|There is a hot topic on two consistency maintenance techniques for Co-editors, Operational Transformation (OT) and Commutative replicated data type(CRDT). Choosing between them for implementing a real-world co-editor is hard.|
Common evidence of OT-supporters is that OT has been widely adopted in industrial products, like Google Docs, Dropbox Paper, etc., and OT is a reliable technique.
Common evidence of CRDT-supporters is that Google Wave OT requires a central server, but CRDT does not have this constraint and is especially suitable for P2P network environments.
So, what is the truth?
A recent paper (https://arxiv.org/abs/1810.02137) reveals the truth.
