> In Flink 2.0, we have introduce DataStream API V2. To verify this feature,
> you should test four scenarios:
> 1. Write a stateful DataStream program, such as WordCount. Use
> ProcessFunction to receive and process data, and use State to store the
> state. You can refer to the documentation:
> # [context and state
> processing|https://nightlies.apache.org/flink/flink-docs-release-2.0/docs/dev/datastream-v2/context_and_state_processing/]
> 2. Write a window aggregation job using the event time extension and verify
> it. You can refer to the documentation:
> # Event Time
> ## [Event Timer
> Service|https://nightlies.apache.org/flink/flink-docs-release-2.0/docs/dev/datastream-v2/time-processing/event_timer_service/]
> ## Examples listed in [FLIP-499: Support Event Time in DataStream
> V2|https://cwiki.apache.org/confluence/x/pQz0Ew]
> # Window
> ##
> [Windows|https://nightlies.apache.org/flink/flink-docs-release-2.0/docs/dev/datastream-v2/builtin-funcs/windows/]
> ## Examples listed in [FLIP-501: Support Window in DataStream
> V2|https://cwiki.apache.org/confluence/x/z4kgF]
> 3. Write a Join job using the BuiltinFuncs#join and verify it. You can refer
> to the documentation:
> #
> [Joins|https://nightlies.apache.org/flink/flink-docs-release-2.0/docs/dev/datastream-v2/builtin-funcs/joining/]
> # Examples listed in [FLIP-500: Support Join in DataStream
> V2|https://cwiki.apache.org/confluence/x/ywz0Ew]
> 4. Write a job define and using the Watermark and verify it. You can refer to
> the documentation:
> #
> [Watermark|https://nightlies.apache.org/flink/flink-docs-release-2.0/docs/dev/datastream-v2/watermark/]
> # Examples listed in [FLIP-467: Introduce Generalized
> Watermarks|https://cwiki.apache.org/confluence/x/oA6TEg]\
