Hi everyone, I'm using postgres 11.4 I have a configuration in which there's one subscriber (slave) node which subscribes to several (4) publisher nodes (master). I noticed one of the master servers keeps lagging behind. I noticed that the replication worker on the master keeps failing on timeouts. When querying pg_stat_subscription on the slave I noticed that last_msg_send_time for this master hardly ever updates.
Could this be starvation? Is there any special configuration on either side (master/slave) that can help reduce that? What's the logic on the slave that chooses from which subscription to process incoming data? How can I further debug this? Thanks, Dan. Sent from Outlook<http://aka.ms/weboutlook>
