For now, Graft suffers from the same minimum payload size of 4KB. However, there are ways to eliminate that. I've filed an issue to resolve this in Graft (https://github.com/orbitinghail/graft/issues/35), thanks for the reminder!

As for the more general question though, by shipping pages you will often ship more data than the equivalent logical replication approach. This is a tradeoff you make for a much simpler approach to strong consistency on top of arbitrary data models.

I'd love to learn more about the approach you took with your sync engine! It's so fun how much energy is in the replication space right now!
