Hi, Kamal. If we don't enable checkpointing, the job will be started with the startup mode each time. For example, the job reads Kafka from the earliest offset and writes to mysql. If the job failover without checkpointing, the tasks will consume Kafka from the earliest offset again.
I think it is best to enable checkpointing to restart job from the position where the job stopped reading.
