Description of PR
After applying the placement constraint allocator in our internal cluster, I found some hotpoint that will effect the scheduling performance as the allocation time metric value increase a lot.
After dumping the flamegraph, the hotpoint is that the
SingleConstraintAppPlacementAllocator.checkCardinalityAndPending
, this should be optimized by like cache or other ways. But the unnecessary nested AND placement constraint may be a small improvement for this case.How was this patch tested?
