Scenario families
Mean across every framework and engine in this upload.
What the workloads measure
The row shape and operation mix decide where each framework spends its time.
Scenario families
- simple baseline row shape
- Shows framework overhead with minimal field complexity, so object creation and query setup dominate.
- canary mixed field and nullable stress
- Wide mixed records amplify casting, hydration, dirty tracking, and adapter metadata overhead.
- int_fixed pure scalar writes
- A low-noise floor. Slow results here usually mean framework machinery is expensive even before text and cast-heavy payloads show up.
- float_fixed numeric conversion paths
- Decimal and float normalization can widen update and verification cost, especially for ORMs that compare serialized values.
- string_fixed predictable text hydration
- Column count and text assignment matter more than payload variability, which makes hydration strategy easier to isolate.
- string_variable application-like text workload
- Variable strings and note fields make this the closest to real CRUD traffic and usually punish heavier active-record layers the most.
Operation shapes
- Warmup vs hot runs
- Run 1 is warmup. Hot-path averages exclude it so boot and metadata setup do not dominate steady-state rankings.
- Insert and indexed schemas
- Indexed tables make writes cost more because every insert and many updates must maintain secondary indexes as well as the row itself.
- Read all vs read probes
- Read All rewards bulk hydration efficiency; random and tail probes expose per-query setup, lookup overhead, and tiny-result inefficiency.
- Update with verification
- Each update shape is followed by a verification read, so dirty-checking, write SQL generation, hydration, and comparison all affect the final time.
- Delete with confirmation
- Deletes are checked afterward. Frameworks that pay extra for follow-up lookups or teardown lose more time here than a bare SQL path.
- Total runtime
- The total runtime metric is effectively a benchmark of the machine plus adapter behavior across the full workload, not just one CRUD verb.
