Environment

We have a core sql server cluster. This cluster contains some databases that get replicated to a load-balanced sql cluster of currently 3 servers. These databases are replicated each 12 hours but will eventually be replicated every 4 hours.

Requirement

On this cluster a new database is created and we need this database to be replicated asap to the load-balanced sql cluster. A delay of seconds or minutes is allowed and writes to this database are currently and in the future low (a few per hour).

Questions

Can two different replication plans coexist side-by-side on the same environment?

Is it possible to setup a second replication routine for this scenario (continuous transaction replication) besides the current replication schema for the existing databases?

Does this create a high risk for a large existing scheduled replication job?

Our DBA says that this replication scenario creates a high risk for the existing replication configuration (2x a day).

My brainwaves

I can't imagine that this minor write activity with continuous transaction replication can create issues for the large existing replication job. I can imagine the other way around that our continuous replication will suffer twice a day due to the large replication job. We are perfectly fine with that as replication is required ASAP during regular operation.
