Wojciech Tyczyński 3030f660a8 Graduate APIListChunking to GA 
Kubernetes-commit: 6acfa3cb4ac876e46ead5ba4772ba18e480435ce
 2023-07-21 11:35:21 +02:00
Andrew Sy Kim f00505bddc priority & fairness: support dynamically configuring work estimator max seats 
Max seats from prioriy & fairness work estimator is now min(0.15 x
nominalCL, nominalCL/handSize)

'Max seats' calculated by work estimator is currently hard coded to 10.
When using lower values for --max-requests-inflight, a single
LIST request taking up 10 seats could end up using all if not most seats in
the priority level. This change updates the default work estimator
config such that 'max seats' is at most 10% of the
maximum concurrency limit for a priority level, with an upper limit of 10.
This ensures seats taken from LIST request is proportional to the total
available seats.

- add plumbing that allows us to estimated "width" of a request
- the default implementation returns 1 as the "width" of all
  incoming requests, this is in keeping with the current behavior.
