_migrations table not replicated

[jeffreywescott]

rethink-migrate seems to have no way to set the replicas attribute when creating the _migrations table (see here), which means that in a real-world production environment, the _migrations table is not being replicated across all nodes in the cluster.

This is a little meta, but one could write a migration for the _migrations table to tag replication for this table, no?

[jeffreywescott]

Interesting idea, @jordanh ... still, I think it would be better as a feature on this module.

[jordanh]

What would you propose as the interface? Configuration options in database.json and/or command line switches?

[jeffreywescott]

Yeah, I think something like numReplicas and numShards in database.json is the way to go.
