Frequently checkpoint failure, could make the flink sql state not clear?

[LakeShen]

Hi community， now I am using Flink sql , and I set the retention time, As I all know is that Flink will set the timer for per key to clear their state, if Flink task always checkpoint failure, are the  key state cleared by timer?

Thanks to your replay.

Hi,

AFAIK, whether a timer will fire is irrelevant to checkpoint success or not.
