Hi,

Would it be possible to switch from protocol A to C and vice versa 
without disconnecting (for instance detach, switch protocol and re-attach)?

This would be useful when alternating between two primaries (only 
protocol C can be used) and a primary/secondary configuration where 
protocol A may increase write throughput on the primary node.

Right now this behaviour does not seem to be supported but I am 
interested if you consider it could be implemented easily.

Thank you.

Cristian
