Online lossless zero downtime upgrades?
I've done it with Cassandra...and yeah Kafka can do it I've heard.
But those can be 30 hour operations even with you ducks in a row, and you better have backup strategies ready.
Fun story, Amazon said rds would be always be zero downtime upgrades. But then came a major version upgrade and .... Surprise it wasn't.
