hey i am new to open source but i want to contribute in this , can you guide me what to do

[kerthcet]

Do you familiar with kube scheduler, if not, this is a little hard for you because the doc is about the mechanism under the scheduler.

[Surajkumar98012]

yeah, I am familiar with Kube scheduler, I learnt about this when I am deep dive into the k8s architecture.

[kerthcet]

Basically, we have several changes to the scheduling queue:

• unschedulingQ -> unschedulingPods
• queueingHint introduced in the recent releases(beta but disabled by default)
• changed some metrics
• changed the background periodical flushing time

I think what we want to do here is just make the document updated with the latest changes.

[Surajkumar98012]

Got it,
let me try, what I can do about it

[Surajkumar98012]

so, I think I need to compare it and update it with latest changes.
