> Support and to CEP's pattern API
> --------------------------------
>
> Key: FLINK-8147
> URL: https://issues.apache.org/jira/browse/FLINK-8147
> Project: Flink
> Issue Type: New Feature
> Components: Library / CEP
> Reporter: Dian Fu
> Priority: Minor
> Labels: stale-minor
>
> Adding API such as {{and}} in CEP's pattern API will let us define patterns
> like {{(A -> B) and (C -> D)}}.
> Its usage looks like
> {noformat}
> Pattern left = Pattern.begin("A").followedBy("B");
> Pattern right = Pattern.begin("C").followedBy("D");
> Pattern pattern = left.and(right)
> {noformat}
> If this makes sense, we should also support APIs such as {{or}} and {{not}}.
