The function is meant to be used by an operator as a last resort to
clean up a consumer group from "ghost" consumers and unblock the group.
At this point the SAC coordinator should work as expected but an upgrade
from a version with known issues can end up with blocked groups. So this
function should help unblock the groups manually.
It can be called like this:
rabbitmqctl eval 'rabbit_stream_coordinator:evaluate_sac_group(<<"/">>,
<<"stream-0">>,
<<"app1">>).'
The actual call is hidden behind the 4.3.0 feature flag. This ensures
all the nodes have been upgraded and are using the latest machine
version.
