> Key: FLINK-5845
> URL: https://issues.apache.org/jira/browse/FLINK-5845
> Project: Flink
> Issue Type: Sub-task
> Components: CEP
> Affects Versions: 1.3.0
> Reporter: Kostas Kloudas
> Assignee: Kostas Kloudas
> Fix For: 1.3.0
>
>
> Currently the keyed and non-keyed operators in the CEP library have different
> implementations. This issue targets to unify them into one.
> This new implementation will always be applied on a keyed stream, and in the
> case of non-keyed usecases, the input stream will be keyed on a dummy key, as
> done in the case of the {{DataStream.windowAll()}} method, where the input
> stream is keyed using the {{NullByteKeySelector}}.
> This is a first step towards making the CEP operators rescalable.
