Subject [jira] [Created] (FLINK-8147) Support and to CEP's pattern API
Date Fri, 24 Nov 2017 12:35:00 GMT
Dian Fu created FLINK-8147:

             Summary: Support and to CEP's pattern API
                 Key: FLINK-8147
                 URL: https://issues.apache.org/jira/browse/FLINK-8147
             Project: Flink
          Issue Type: Bug
          Components: CEP
            Reporter: Dian Fu

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
Pattern left = Pattern.begin("A").followedBy("B");
Pattern right = Pattern.begin("C").followedBy("D");
Pattern pattern = left.and(right)
If this makes sense, we should also support APIs such as {{or}} and {{not}}.
