What are requirements for a replication?
- max latency time
- volume of changes (bytes/time)
- one direction / by-direction / multi-direction
- synchronous/asynchronous
- some specific/exotic data types
- is any transformation of values required
- is any filtering of rows based on column values or other criteria like user or time required
- other?

Replication of what? Synchronous or asynchronous?
Real time or with a latency?
What volume of data per unit of time?
What requirements around switchover and/or failover?
What requirement with respect to failure detection?
What requirement in terms of reconciling differences between the two?

We are missing a lot of critical information.
