Well the system had Postgres -> Debezium -> Kafka -> CustomApp -> Client. If data stopped flowing through the system, I would have to examine each component to figure the issue out. They'd mostly turn out to be Kubernetes network issues such as Kafka brokers not being able to talk to each other, or Debezium not being able to contact Kafka. This was too painful to run when all we wanted was notifications of changes on Postgres.

If you drop me a note with your email, I'll make sure to get in touch with you when our solution using Postgres LR exposed over WebSockets (and more) is out :)
