--------------------------------------

             Summary: CEP Pattern supports definition of the maximum time gap between events
                 Key: FLINK-27392
                 URL: https://issues.apache.org/jira/browse/FLINK-27392
             Project: Flink
          Issue Type: Improvement
          Components: Library / CEP
    Affects Versions: 1.16.0
            Reporter: Nicholas Jiang
             Fix For: 1.16.0


At present, Pattern#withIn defines the maximum time interval in which a matching pattern has to be completed in order to be considered valid. The interval corresponds to the maximum time gap between first and the last event. The maximum time gap between events is needed in the certain scenario, for example, purchases a good within a maximum of 5 minutes after browsing.
