Hi @macsko 👋 -- this is Graziano (@graz-dev) from the v1.35 Communications Team!

Just a friendly reminder that we are approaching the feature blog "ready for review" deadline: Friday 21st November. We ask you to have the blog in non-draft state, and all write-up to be complete, so that we can start the blog review from SIG Docs Blog team.

If you have any questions or need help, please don't hesitate to reach out to me or any of the Communications Team members. We are here to help you!

graz-dev

Some nits, the overall article looks good and easy to read.
Thank you!

## How Gang Scheduling Works

## How gang scheduling works

Here would be useful to have an example of the behavior.
If you configure this way, and these conditions are met then this will happen...

Do you mean modifying the current gang scheduling steps or adding a standalone example after the high level description?

+Note that you may need to review your kube-scheduler configuration
+to ensure default topology spread constraints are not implicitly disabling batching for your workloads.
+
+See the [docs](TODO) for more details about restrictions.


I presume we should wait for these to land in the dev-1.35 branch?

Exceptions are not hard to get, IMO (the deadline for blog articles is formally today).

Yes, I think we can merge it as a draft if needed and then add the link to the doc later before publishing it.
