----------------------------------------
[~monster#12], we will submit the proposal about the dynamic rule support for
the CEP to the community. We're happy to discuss the design of the the dynamic
rule feature. Do you have interest to make attention to the FLIP?
> 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
