------------------------------------
Fix Version/s: 1.12.0
Release Note:
This is formatted in Markdown for easy inclusion in the release post.
In Flink 1.12 the default stream time characteristic has been changed to
`EventTime`, thus you don't need to call this method for enabling event-time
support anymore. Explicitly using processing-time windows and timers works in
event-time mode. If you need to disable watermarks, please use
`ExecutionConfig.setAutoWatermarkInterval(long)`. If you are using
`IngestionTime`, please manually set an appropriate `WatermarkStrategy`. If you
are using generic "time window" operations (for example
`KeyedStream.timeWindow()` that change behaviour based on the time
characteristic, please use equivalent operations that explicitly specify
processing time or event time.
Resolution: Fixed

> After FLINK-19317 and FLINK-19318 we don't need this setting anymore. Using
> (explicit) processing-time windows and processing-time timers work fine in a
> program that has {{EventTime}} set as a time characteristic and once we
> deprecate {{timeWindow()}} there are not other operations that change
> behaviour depending on the time characteristic so there's no need to ever
> change from the new default of event-time. Similarly, the {{IngestionTime}}
> setting can be achieved in the future by providing an ingestion-time
> {{WatermarkStrategy}}.
