ZhuoYu Chen updated FLINK-25170:
--------------------------------
Description:
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
