----------------------------------
Assignee: boshu Zheng
> Do not expose keyed operations on ProcessFunction.Context
> ---------------------------------------------------------
>
> Key: FLINK-9529
> URL: https://issues.apache.org/jira/browse/FLINK-9529
> Project: Flink
> Issue Type: Sub-task
> Components: Java API
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Assignee: boshu Zheng
> Priority: Major
>
> Currently, the {{ProcessFunction}} provides a {{Context}} object from which
> on can access the {{TimerService}}. The {{TimerService}} allows to register
> timers if one operates on a keyed stream. If it is not a keyed stream, then
> this operation fails. Recently, we added a {{KeyedProcessFunction}} which
> captures this semantic difference. I would propose to clean up the
> {{Context}} interface to give only access to supported operations when
> operating on a non-keyed and keyed state respectively.
