Description
Earlier we made fixes for #1939 and #2452
As part of the above issues, we added more swift way to handle concurrency #2737
and reduce bursts in pod specialization when initial bulk calls are made to the function.
In the earlier approach, we used all the capacity of a single pod(actual + virtual) and then used to specialize further pods.
This causes failure of requests if specific pod specialization fails.
This PR changes the approach a bit and uses concurrency aggressively until a point it is available(to the limit). Once we exhausted concurrency we consider using the virtual capacity of the pods until specialization finishes.
Combining this and old approach will ensure we specialize pods as much as possible and then switch to virtual capacity up to request per pod limit.
Which issue(s) this PR fixes:
Fixes #1939
