Fangliang Liu updated FLINK-33079:
----------------------------------
Description:
The gap between the checkpoint timeout and the interval settings is too large
https://nightlies.apache.org/flink/flink-docs-master/docs/dev/datastream/fault-tolerance/checkpointing/
Some users will think that the documentation is the optimal solution and refer
to this demo setting, and the result is that the actual checkpoint interval is
not as expected because of the checkpoint-timeout
!image-2023-09-13-14-17-12-718.png|width=682,height=468!
The following situation occurs when the checkpoint interval is set to 20s and
the checkpoint timeout is set to 10 minutes.
!image-2023-09-13-14-19-05-493.png|width=1637,height=757!
So lets do some optimization in the checkpoint example(e.g. checkpoint interval
60s, checkpoint timeout 60s), or provide more documentation for setting up
checkpoints config.
