Hello,i am learning the flink cep library in flink,is there a way we can remove the pattern from the group of patterns from the flink streaming job?

Are you saying that you want to dynamically change the pattern while the job is running?

No,just want to remove the pattern even by restarting the job from the savepoint.currently i am able to add new pattern in that but removing the existing pattern after a restart it does not allow and job never get started.

Do you get an error (perhaps in the logs?) when you try this?

Yes,whenever if any pattern is removed ,after restart i give exception -NFA does not contain the state etc

I don’t know enough about the CEP internals to know for sure if this will work, but I would try specifying the

--allowNonRestoredState

option when restarting. That might be enough to resolve this issue.

Have tried this but still it searches for the state for the deleted patterns
