Dian Fu created CALCITE-2033:
--------------------------------

             Summary: Support followed by in pattern definition for MATCH_RECOGNIZE
                 Key: CALCITE-2033
                 URL: https://issues.apache.org/jira/browse/CALCITE-2033
             Project: Calcite
          Issue Type: Bug
            Reporter: Dian Fu
            Assignee: Julian Hyde


The [doc|https://docs.oracle.com/database/121/DWHSG/pattern.htm#DWHSG8986] has already defined
pattern operator {{Concatenation}}. For example, pattern {{A B}} means that events matching
pattern {{A}} and {{B}} should occur successively. There are also many use cases which require
patterns to match events which not occur successively.
