Dian Fu commented on CALCITE-2033: ---------------------------------- I have created a PR which introduces a new operator {{->}} to support this. May be other operators? Any advice? For example, for pattern {{A -> B}}, it means that there may be other kinds of events between the events matching pattern {{A}} and {{B}}. https://github.com/apache/calcite/pull/558 Hi [~julianhyde] [~ransom], what do you think about this functionality? If you think it makes sense, could you help to take a look at this PR? Thanks a lot. > 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}}.

There are also many use cases which require patterns to match > events which not occur successively. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
