First, scheduling and allocation performance. Pull request 142406 brings a series of allocator optimizations for Dynamic Resource Allocation, building on scheduler performance tests to enable future features. Related work unifies Pod Group handling in the scheduler queue in 143354 to reduce duplication, and…
Second, API server efficiency and policy enforcement. Pull request 131862 changes API server watch to avoid fetching prior values from storage when not needed, while companion cacher cleanups in 143493, 143520 and 143515 expand coverage and remove unused helpers.
