> cep supports dynamic rule updates
> ---------------------------------
>
> Key: FLINK-25170
> URL: https://issues.apache.org/jira/browse/FLINK-25170
> Project: Flink
> Issue Type: New Feature
> Components: Library / CEP
> Reporter: ZhuoYu Chen
> Priority: Major
>
> External loading: Usually the rule engine has a special rule management
> module to provide users to create their own rules, for Flink tasks need to go
> external to load rules
> Dynamic update: need to provide timing to detect whether the rules change
> History state cleanup: in pattern matching is a series of NFAState If the
> rules change, the states are useless and need to be cleaned up
> Easy API: Different business developers may have their own rule management,
> timing policies, etc., so they need to provide an easy-to-use API to the
> outside world
