feat(bench): JMH microbenchmarks module + manual CI job
CEO plan v1 polish — закрывает gap "JMH performance benchmarks в CI для
baseline + Redis-enabled scenarios".
New module:
- ordinis-bench/ — JMH 1.37 microbenchmarks. Gated behind `bench` Maven
profile в parent pom — НЕ строится при обычном `mvn package` (default
CI остаётся быстрым).
- maven-shade-plugin под `bench` profile собирает uber-jar
`target/benchmarks.jar` (86 MB, ~12 sec build).
- LineageBenchmark covers hot paths из dict-relationships-v2:
* parseRef_simple / withSchemaButNoOnClose / withOnClose
* onCloseAction_block / cascade / null
* schemaTraversal_findRefs (40 props, 5 refs — realistic shape)
Baseline numbers (M3 MBP, JDK 25, single thread):
- onCloseAction_*: 0.6–12 ns/op
- parseRef_*: 20–93 ns/op
- schemaTraversal: 417 ns/op (~83 ns per ref на 40 props)
Cumulative budget for findSchemaDependents на 40 dicts × 40 props × 5 refs:
~17 µs. p99 endpoint SLO = 200 ms — запас 4 порядка. README documents
budget + 2x regression alarm.
CI integration:
- New job maven-bench (stage: test). Manual trigger only:
* RUN_BENCH=true variable, OR
* web pipeline source с manual click.
- Default CI (push/merge) НЕ запускает bench — slow + noisy в history.
- Output artifacts: bench-results.json + bench-results.txt (5 day expire).
- Quick smoke config: 1 fork, 2 warmups, 3 measurements × 2s = ~5 min total.
Side effect: ReferenceValidator.parseRef static methods переведены из
package-private в public. Они и так часть public ParsedRef contract —
visible to bench module без изменения design intent.
Verify:
- mvn -P bench -pl ordinis-bench -am package: BUILD SUCCESS (12s).
- java -jar benchmarks.jar -f 1 -wi 1 -i 2 Lineage: all 7 benchmarks
exec'ятся, valid ns/op numbers.
- mvn -pl ordinis-rest-api -am test: 106/106 PASS unchanged.
- glab ci lint: clean.
README в ordinis-bench/README.md документирует:
- baseline numbers + 2x regression budget
- local run options (smoke / full / GC profile / JSON output)
- when CI bench runs (manual web trigger)
- difference vs k6/wrk (HTTP load tests are different layer, both needed)
- how to add new benchmark
