Re: Apache Flink - CEP vs SQL detecting patterns
Hi, Unfortunately those are just ignored. The timed out partial matches are not emitted.

Re: Apache Flink - CEP vs SQL detecting patterns
Dawid: So, what happens when there is a timeout - is there any value/field in the resulting data stream that indicates that this was a timeout ?

Re: Apache Flink - CEP vs SQL detecting patterns
Hi Mans, Yes you are right. That feature is not available in SQL, as there is no such feature in SQL standard. The only addition to SQL standard we introduce so far is the WITHIN clause. We might introduce the timed out patterns some time in the future, but personally I am not aware of such plans.

Apache Flink - CEP vs SQL detecting patterns
Hi: I am looking at the documentation of the CEP and there is way to access patterns which have timeout. But I could not find similar capability in the Table and SQL interface detecting patterns. I am assuming that the CEP interface is more comprehensive and complete than the SQL/Table interface. Please let me know if I have missed anything. Thanks Mans
