There are a variety of solutions to this but CRDTs are a very good one (CRDTs solve your problem (https://en.wikipedia.org/wiki/Conflict-free_replicated_data_...). If the operations you're doing commute (that is a ○ b = b ○ a, e.g. the order in which you apply the operations doesn't matter) then one could apply all operations in parallel, and only send the final result of doing them all. Casandra uses LWW-Element-Set CRDTS to solve this exact problem (https://cassandra.apache.org/doc/latest/cassandra/architectu...).
