------------------------------------

             Summary: Do not expose keyed methods 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


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.
