aitozi created FLINK-9507: ----------------------------- Summary: 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: CEP Affects Versions: 1.5.0 Reporter: aitozi Assignee: aitozi Fix For: 1.6.0
When we use the cep to describe a condition about the events that has been matched, we have to call the method {code:java}getEventsForPattern{code} 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] -- This message was sent by Atlassian JIRA (v7.6.3#76005)
