A colleague of mine found some hint under “Avro type” [2] in the State
evolution schema page:
“Example: RocksDB state backend relies on binary objects identity, rather than
hashCode method implementation. Any changes to the keys object structure could
lead to non deterministic behaviour.”

Hi Dylan,
thanks for the investigation. I can now also reproduce it my code. Yes,
this is a bug. I opened

Thanks,

@Yang: I think this would be valuable to document. I think it's a natural
question to ask whether you can have standby JMs with Kubernetes. What do you
think? If you agree, we could create a JIRA ticket and work on the "official"
docs for this.

Hey David,
this is a good catch! I've filed a JIRA ticket to address this in the docs
more prominently: https://issues.apache.org/jira/browse/FLINK-21073
Thanks a lot for reporting this issue!

Thanks a lot for your message.
Why is there a difference of 5 minutes between the timestamp of the job
submission from the client to the timestamp on the JobManager where the
submission is received?
Is there any service / custom logic involved in the job submission? (e.g. a
proxy in between, that

I was trying to get rid of the deprecation warnings about

proceed.
My current code does the following:

Timo,
Will do! I have been patching in a change locally that I have a PR [1] out for,
so if this will end up in the next 1.12 patch release, I may add this in with
it once it has been approved and merged.
On a side note, that PR has been out since the end of October (looks like I

Since our CI system is able to build Flink, I believe it's a local issue.
Are you sure that the build is failing when you build Flink from the root
directory (not calling maven from within a maven module?)

Hi Dylan,
I can help with a review for your PR tomorrow. In general, I would
recommend to just ping people a couple of times that have been worked on
the component before (see git blame) to get a review. We are all busy

through our secure repository. I’ve included the JobManager and client

I have a Streaming process where new directories are added daily in S3.

If I start the process, it won't pick up anything other than the

Hi,
We recently migrated from 1.9.1 to flink 1.11 and notice the new job cannot
consume from savepoint taken in 1.9.1. Here is the list of operator id and
max parallelism of savepoints taken in both versions. The only code change
is version upgrade.
savepoint 1.9.1:
```
Id: 8a74550ce6afad759d5f1d
I sent this a little prematurely. Will the streaming process find new
directories under the parent?
If the input path is
s3://foo.bar/
and directories are added daily, should I expect that the newly added
directories+files will get processed?
Thanks!

Hi,
I think you could try something like this
firstStream
.coGroup(secondStream)
.where(_.id)
.equalTo(_.id)
.window(TumblingEventTimeWindows.of(Time.seconds(1)))
.with(new MyCogroupFunction())
.uid("myCoGroup")

Yes. I agree with you that it is valuable to document how to start multiple

Thanks for your enthusiasm to figure out the root cause. The key difference is
that RocksDB holds binary objects which are only defined by the serialized
bytes while Fs/MemoryStateBackend holds objects in pojo format which are

thanks a lot for providing me with the full logs.
The JobManager actually received 2 job submissions.
There are 2 relevant log messages.
