- Which pinned versions, topology and service tier fit the intended workload?
- What are measured correctness, latency, recovery and total operating cost under that workload?
Applicability
Unpinned upstream documentation accessed 2026-09-14; pin engine, extension and service versions before use.. Operator manages deployment, backups and upgrades. This target excludes extensions..
Excludes: Runtime verification; Workload benchmarks and cost comparisons; Unlisted extensions, service tiers and deployment configurations.
Verification plan
- Pin the target configuration and define workload fixtures, access and budget.
- With authorization, test concurrent writes and recovery against explicit correctness expectations.
- For vector workloads, measure filtered recall against an exact-search baseline and record index settings.
