Till Rohrmann created FLINK-3317: ------------------------------------ Summary: Add timeout handler to CEP operator Key: FLINK-3317 URL: https://issues.apache.org/jira/browse/FLINK-3317 Project: Flink Issue Type: Improvement Components: CEP Affects Versions: 1.0.0 Reporter: Till Rohrmann Priority: Minor
Currently, event sequences which exceed the defined pattern timeout will be discarded. However, in some cases the user might be interested in getting to know when such a timeout occurred to return a default value for these event sequences. Thus, the pattern API should be extended to be able to define a timeout handler. Furthermore, the {{NFA}} has to be extended to also return the discarded event sequences. The {{CEPOperator}} would then call for every discarded event sequence the timeout handler. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
