Replication of some/all datoms to other dbs

I’m providing a global service and I want to reduce latency.

One way to do this might be to create N cloud dbs in different regions and replicate a users data from the original db to the others. This could be for all data or just on-demand when the user requests a region change.

What are the options for architecting something like this? Has anyone already done something like this with Datomic Cloud?
