2 node Mysql with an arbitrator

Is it possible to setup a 2 node cluster with a 3rd node as arbitrator in Everest, as described in the xtradb docs?

Hey @Joshua_Sierles ,

right now - no.
Mostly because we don’t support arbitrators in our Operator (which is fueling Everest).

Even arbitrators are a thing, we usually do not recommend to use them as they significantly impact availability. For example, for MongoDB, we recommend to use arbiters with 4+1 configuration (not 2+1).
