Do you plan to make it more performant in the future? I mean calling
doveadm (and ssh) for every change -even when they are aggregated- seems
to be very resource intensive, it won't keep up on a machine with a lot
of modifications happening every seconds.
It would be good to have constantly running daemons on both sides to
eliminate the high startup/teardown costs.
(if I understand things correctly)
Thanks for working on this.
