somehow persist the GenericInMemoryCatalog. I am afraid it is not

Hi,
In the streaming API, the biggest difference is that if you do not

Do you mind sharing the code how do you register your metrics with the
TriggerContext? It could help us identify where does name collisions
come from. As far as I am aware it should be fine to use the
TriggerContext for registering metrics.

Therefore the cleaning logic in onTimer effectively uses the same logic.
If I understand it correctly, this trick was introduced to deduplicate
the method.
There might be a bug somewhere, but I don't think it's where you
pointed. I'd suggest to first investigate the progress of watermarks
Hi,
I know Jingsong worked on Flink/Hive filesystem integration in the
Table/SQL API. Maybe he can shed some light on your questions.

Generally speaking you should be fine when adding/removing fields in a
projection. I'd say it is the only somewhat safe change, but it is not
guaranteed in all cases nevertheless.

Basically you are facing exactly the same problem as described in the

Hi Jiazhi,
Could you elaborate what exactly do you want to achieve? What have you
tried so far?

Hey,
Why do you say the way you did it, does not work? The logs you posted
say the classes cannot be handled by Flink's built-in mechanism for
serializing POJOs and it falls back to a GenericType which is serialized
with Kryo and should go through your registered serializer.

The best I can do is point you to the thread[1].
I am also cc'ing Yuan who is the release manager for 1.12.2.
