what is the difference between db-mirror and db-replicate?

db-mirror provides a full zdb replication in a way that master will duplicate all operations to the slave.

db-replicate is another way which enable some trigger/update on specific actions and not necessary have an exact copy of the zdb, you can only trigger on specific namespace or wait on deletion. It's a way to know that some changes occurred without receiving a copy of everything (less chatty but client-side decision).

All of this will be documented later, when tools will be stable.
