I believe that Redis supports CRDTs (https://redis.com/blog/diving-into-crdts/) for its active/active geo-replication, and they're supposed to be pretty fast. ...but it's important to note that CRDTs as used by Redis (and as defined by, for example, https://arxiv.org/pdf/1806.10254.pdf) really just means that you've defined a way to consistently resolve conflicts - it doesn't necessarily mean the all-singing-all-dancing collaborative text editing that a lot of people seem to be assuming. For example, as defined in the paper above, simple "last write wins" is a CRDT.

Slightly pedantic, but I think you'll actually find that all of these are CRDTs. If you read "Conflict-free Replicated Data Types: An Overview" (https://arxiv.org/pdf/1806.10254.pdf), it refers to both last write wins and "record all versions of the data" as CRDTs in 2.1.1. My understanding is that "CRDT" really just means that you've defined how you're going to resolve conflicts consistently (see criteria in s2.2 of the paper above).
