------------------------------------
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.
