Hi Thomas, We currently don't have such a feature of adding and removing

Hi Flavio,
Thank you for the information.
So how do you handle than the following scenario?

cannot talk to 3,4 and 5. Will server 1 and 2 do a new leader election for

have one yet), and will make progress independently. Once the segmentatio
No problem, we really appreciate your feedback -- keep it coming.
