You could check the relationship between max parallelism and bytes of key
group as below:
--
max parallelism | bytes of key group
128 | 1
32768 | 2

So I think the cost will be very small if the real key length is

the max parallelism can be divided by the parallelism whenever I want to

because the number of key groups will not differ too
Hello Team, I am fine tuning my application which can adjust parallelism
automatically based on traffic and EMR auto-scaling will be adding more cores
as needed.
I am trying to set max Parallelism but I always see its working with default

Yes, it is possible, please refer to [1] and [2] for API details.

Hi everyone,
I have some questions regarding max parallelism and how interacts with
deployment modes. The documentation states that max parallelism should be "set
on a per-job and per-operator granularity" but doesn't provide more details. Is
it possible to have differen

Hi Flink community,
most likely I'm missing something but I failed to verify the setting of the
max-parallelism (# key groups).
Is there a way to check the value for a job? I checked the following places
without finding it.
1. Flink UI: Job Configuration
2. Flink UI: SubTasks of a

-operator` uses `flink run`(I found
this in `flinkcluster_submit_job_script.go`) to submit job to cluster. This
command already cover the bridge work, so I think it should just work in
your case.

Hi all,
Sorry for the basic question, but is it possible to set max
parallelism using the flink conf file, rather than explicitly in code:
https://ci.apache.org/projects/flink/flink-docs-stable/dev/parallel.html#setting-the-maximum-parallelism
Need this for a PR I am working on for the flink
Thanks!

If you find that anything is missing, feel free to report it here.
The PRs will be merged later today.

Hi guys,
I would appreciate if someone could explain to me what's the difference
between those two.
The current description refers to "dynamic scaling", and yet I can't find
anything about it in Flink's docs.
Best regards,

If you don't configure anything, we compute somewhat sane defaults in
order to allow scaling up later:

Hi all,
I can't seem to find in the documentation how to set the maximum
parallelism for rescaling keyed state.
Can anyone help me out here?
