Subject Checkpoint recovery and state external to flink
Date Mon, 04 Mar 2019 20:08:33 GMT
What happens when the flink job interacts with a user managed database and hence has some state
outside of flink? In these situations when a flink job is recovered from last successful checkpoint,
this external state will not be in sync with the recovered flink state. In most cases it will
be ahead of the recovered flink state. Any recommendations or best practices to follow here?
I am assuming it must be very common for flink applications to interact with external systems
(databases, message systems etc.)
