Fair acquisition repeatedly scans the entire job store and rebuilds eligible groups for every claim. Build ordered group backlogs and active counts once per queue acquisition, then advance the selected group and update active counts and round-robin sequences after each claim. Cache definition eligibility within the locked acquisition and invalidate it after each successful claim so rate and concurrency limits remain enforced.
Use dictionary lookup for exact job handles, apply query filters and paging before copying records, and count monitoring states in one pass. Add six regression cases covering exhausted definition limits and request capacities across groups, noisy-group reclassification within a batch, and exact-handle filters with updated queue metadata.
Performance
Local Release microbenchmark on .NET 10.0.13, compiled with SDK 11.0.100-preview.7.26381.103. Medians of 11 measurements after three warmups, excluding setup, disposal, and explicit GC. Each measurement uses a fresh store containing 50,000 jobs: 5,000 due pending jobs and 45,000 succeeded jobs, split across two definitions and 20 groups in one queue. Acquisition batch size is 64; filtered paging returns 25 pending jobs of one definition after skipping 100. Results are workload-specific and do not measure contention.
Fair acquisition allocations decrease from 144,109,704 to 569,656 bytes (99.6% reduction).
