Hi Community, I need some advice on upgrading the application logic in our Apache Flink cluster without causing any downtime. We're using Flink for our most important data pipeline, and we need to keep upgrading the application logic to meet our business needs. However, we're worried about the downtime that could affect our users.
I know it might not be possible to achieve zero downtime in the current Flink version, but I think many users have faced the same problem. I'm wondering if it's possible to achieve that in future, and if so, what's the possible directions? Thanks a lot for your help! Best regards, Ruibin
