Why do you want a full sync?
Kind regards,

List members,
I plan on updating my 3 node multi-primary instances and want to have a
full resync done when each instance is rebuilt and rejoined to the
cluster. Currently, I have both config and DIT fully replicated between
all instances. When I rebuild each node, it will have all of the
configs in place to be a part of the cluster. What I would like to have
is all the data pushed to the newly built, but empty, instance.
I have a process that is somewhat brute force, where all data is
exported, stripped of entryCSN and contextCSN values, then added back to
the newly built instance. This would require that the other instances
be stopped or otherwise not take any updates during the transition. I
would like to avoid this disruption in service, if at all possible.
Is there a way to have a full resync done when a rebuilt instance that
has no data rejoins a cluster?
Thanks in advance,
Brendan Kearney

I don't have concerns about performance or answering/responding, as the
cluster is load balanced. I will not have the newly built instances
available in the load balanced pool while the data is being updated on it.
It's not that I want a full sync, but that i have to have one. The
dataset will be blank upon rebuild and the newly built instance will
have no data to provide when queried.
Thank you,
Brendan Kearney
