------------------------------------
Summary: Make clearer distinction between event time and
processing time
Key: FLINK-3536
URL: https://issues.apache.org/jira/browse/FLINK-3536
Project: Flink
Issue Type: Improvement
Components: DataStream API
Reporter: Till Rohrmann
Priority: Minor
If you define your own windows it is easy to mix up the time characteristic
with the wrong set of predefined {{WindowAssigners}}. You cannot use processing
time with a {{TumblingTimeWindows}} window assigner, for example.
Neither from the name of {{TumblingTimeWindows}} nor from the JavaDocs it is
clearly obvious that this {{WindowAssigner}} can only be used with event time.
I think it would be better to rename the event time window assigner to
something like {{TumblingEventTimeWindows}}. Additionally, we could extend the
JavaDocs a bit, since not everyone knows that "based on the timestamps" means
based on event time.
