> Separate NFA-state from NFA in CEP library
> ------------------------------------------
>                 Key: FLINK-8725
>                 URL: https://issues.apache.org/jira/browse/FLINK-8725
>             Project: Flink
>          Issue Type: Bug
>          Components: CEP
>    Affects Versions: 1.4.0, 1.5.0
>            Reporter: Aljoscha Krettek
>            Assignee: Aljoscha Krettek
>            Priority: Major
> The CEP library currently serialises the static parts of the NFA in the state for each
key. This is wasteful, because that part is static and problematic because the static part
can contain user code in the form of filter functions.
> We should only serialise the dynamic state of the NFA (current states, seen elements).
