David Anderson commented on FLINK-18797:
----------------------------------------
[~rmetzger] No, I only looked at keyBy.
You're right, we should rework the examples so they don't use any deprecated
methods. I wonder if it be possible to set up something like checkstyles so
that the examples fail if they are using deprecated methods.
> docs and examples use deprecated forms of keyBy

> AsyncIOExample.java
> SideOutputExample.java
> TwitterExample.java
> GroupedProcessingTimeWindowExample.java
> SessionWindowing.java
> TopSpeedWindowing.java
> WindowWordCount.java
> WordCount.java
> TwitterExample.scala
> GroupedProcessingTimeWindowExample.scala
> SessionWindowing.scala
> WindowWordCount.scala
> WordCount.scala
> There are also some uses of keyBy("string"), which has also been deprecated:
> dev/connectors/cassandra.md
