---------------------------------
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:
# docs/content/docs/dev/datastream-v2/context_and_state_processing.md
2. Write a window aggregation job using the event time extension and verify it.
You can refer to the documentation:
# Event Time
## docs/content/docs/dev/datastream-v2/time-processing/event_timer_service.md
## Examples listed in [FLIP-499: Support Event Time in DataStream
V2|https://cwiki.apache.org/confluence/x/pQz0Ew]

3. Write a Join job using the BuiltinFuncs#join and verify it. You can refer to
