Definitely a tricky problem for CRDTs. A possible solution is outlined in the OpSets paper; https://arxiv.org/abs/1805.04263 https://arxiv.org/abs/1805.04263 I hope that there are existing implementations of OpSets that perform well. I find the solution laid out in that paper to be really elegant and beautiful.
