Hello,Community:
When I import flink-release-2.0-preview1 source to Intellij Idea,some
imported class found cannot be located,and I post them as follows,are they
imported from some pre-built modules or they just lay somewhere of the project.
Thanks,guys.

Thank you,Zakelly.
Seems that versions before 2.0-preview just handle the state I/O with the user

Hi,Community:
I wonder if there any plan to develop flow model based autoscaling
feature?
A possible Flow model based autoscaling mechanism may work as follow
steps:
1.take flow metrics samples from operators,maybe other features.
2.infer operators to be tuned and associated operator parallel

Are there any approaches to add with clause to flink table definition in

Hi,Community:
Does Flink upload states and inflight buffers within the same
opratorchain using the same connection (instead of per connection per operator)?
Thanks,Zhanghao.
I think it's the async upload mechanism helped mitigating the in flight buffers
materialization latency,and the execution vertex restarting procedure just
reads the in flight buffers and the local TaskStateSnapshots to make its
job done.

Hello,Community: Why doesn't flink store in flight buffers to local disks
when it checkpoints?
Thanks.
Thanks,nacisimsek.I will try your suggestion.

Hello,guys:
Does Flink transform all operators(including source operator) to
OperatorChain even disableoperatorchaining was set to true and even the
OperatorChain contains only one single Operator.
Thanks.

Thanks,Rion.I roughly understand.And I still want to know whether the
deployment of Adaptive Scheduler relies on Kubernetes? Are
there any cases of deploying Flink Adaptive Scheduler on bare metal
machine?
Appreciated again.

Hello,Community:
I??ve recently started using the Flink Kubernetes Operator,and I'd like
to know if CPU and Job Parallelism autoscaling are supported without restarting
the whole job,if it??s supported, please tell me how to configure and deploy
it.
Thanks.

Hi??Team??
I was wondering how to get flink accumulated sink record count(just like the
flink UI displays),any help would be appreciated.
For example, operator state and checkpoint listener of flink sql
runtime.I'm trying to modify flink sql compiled behavior
programmatically and get corresponding flink sql runtime.

Is there any approach to get flink sql runtime via api ?

Hi,Team:
Does Flink really discard replayed duplicated records via record timestamp as
the paper Lightweight Asynchronous Snapshots for Distributed Dataflows
states "To achieve this we can follow a similar scheme to SDGs [5] and mark
records with sequence numbers from the sources, thus, every do
