Description

Hi. I'm trying to setup high availability on 4-nodes cluster(coordinator+replica and two workers). When I stop PG on the first citus worker, the coordinator shows me the warning but DML still works. In the opposite situation, when I stop PG on the second citus worker, I see the same warning but DML does not work. Which citus configuration parameter defines the difference in the behavior?
I use PG 13 and Citus 10.2 on Ubuntu 20.04. Thank you in advance.
