Summary: Make CEP operators rescalable (was: Make keyed CEP operator
rescalable)
> Make CEP operators rescalable
> -----------------------------
>
> Key: FLINK-5420
> URL: https://issues.apache.org/jira/browse/FLINK-5420
> Project: Flink
> Issue Type: Bug
> Components: CEP
> Affects Versions: 1.2.0
> Reporter: Kostas Kloudas
> Assignee: Kostas Kloudas
>
> {{AbstractKeyedCEPPatternOperator}} uses the old state snapshotting
> interfaces that make the operator non-resealable. The operator uses state to
> keep track of all the in-flight keys. When a watermark arrives the buffers
> are checked for all keys and those that can be processed are processed. We
> could change this to use the abstract timer system instead.
