Hi Dineth,
In the UI of flink there is pages for details for the checkpoints[1], could you
have a look this UI
to see which part of checkpoint took long time~?
Best,

Checkpoint fails randomly with a timeout. Many times this happens when
there are no other events coming into flink (at night). Most of our
incoming data is during the daytime, and at night there are usually no
events. Many of these failures have been at night. We had set a checkpoint
timeout of 2 m
