Hi
Currently, checkpoint discard logic was executed in Executor[1], maybe
it will not be deleted so quickly

Best,

Thanks.
I have some jobs with the checkpoint interval 1000ms. And the HDFS
files grow too large to work normally .
What I am curious about is, are writing and deleting performed
synchronously? Is it possible to add too fast to delete old files?

Hi
No matter what interval you set, Flink will take care of the
checkpoints(remove the useless checkpoint when it can), but when you set a
very small checkpoint interval, there may be much high pressure for the
storage system(here is RPC pressure of HDFS NN).
Best,
