Flink Jira Bot updated FLINK-9507:
----------------------------------
Labels: auto-unassigned stale-major (was: auto-unassigned)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Introduce ReduceFunction to CEP to minor the cost for IterativeCondition
> ------------------------------------------------------------------------

> Key: FLINK-9507
> URL: https://issues.apache.org/jira/browse/FLINK-9507
> Project: Flink
> Issue Type: Improvement
> Components: Library / CEP
> Affects Versions: 1.5.0
> Reporter: Aitozi
> Priority: Major
> Labels: auto-unassigned, stale-major
>
> When we use the cep to describe a condition about the events that has been
> matched, we have to call the method "getEventsForPattern" to extract the
> partly matched elements from the sharedBuffer in RocksDB, which is very cost,
> I think we can introduce a ReduceFunction on the pattern desc to allow us to
> aggregate the value in advance. Is this practical ？ What's your guys
> opinion? [~kkl0u] [~dawidwys]
