Jark Wu commented on FLINK-18642:
---------------------------------
This is supported in blink version, but this feature is removed when blink
merging. [~dwysakowicz] mentioned the reason. If we want to extend the syntax,
we should cooperate with Calcite community. Let's keep this issue open and see
if it is needed by others and if someone would like to work on it.
> Support emitting timed out patterns in MATCH_RECOGNIZE

> Whether flink SQL CEP supports output matching timeout。 has not been
