# One Kafka for the measurement application. One broker is enough: what gets run several times is
# the runner instance, not the broker.
#
#   docker compose -f runners/kafka-streams/measurement/docker-compose.yml up -d
#
# group.min.session.timeout.ms is lowered because a broker refuses a session timeout below it, and
# how quickly the group notices a departed instance is the floor on how quickly its work moves. The
# default of 6s would put a floor under every measurement of recovery.
