[jira] [Commented] (FLINK-18642) Support emitting timed out patterns in MATCH_RECOGNIZE

    [ https://issues.apache.org/jira/browse/FLINK-18642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17161065#comment-17161065 ] 

Dawid Wysakowicz commented on FLINK-18642:
------------------------------------------

The MATCH_RECOGNIZE clause has no notion of timed out patterns. This would be a new addition to the SQL standard.

It is not in the docs because it is not supported and there was not work to support such clause or any similar one.

> Whether flink SQL CEP supports output matching timeout。 has not been introduced on the official website in several versions. I don't know if it's because of the Calcite version. The statement ONE ROW PER MATCH WITH TIMEOUT ROWS is not supported。
