Configuration parameter recommendations for different routers & fail-over scenarios w detailed discussion of GTID choices would be very helpful.

Customers sometimes (as in associated support case) request recommended configurations when starting out. Documenting GTID configuration details like that any transaction on a slave can break failover due to the master_use_gtid = current_pos requirement, guidance on configuring domain IDs,and some enumeration of the implications of strict mode , for example, would be very helpful guidance.
