Boundary tests cover 0, 1, 39, 40, 41, 80, and 81 candidates, including +a partially filled last batch. These are request-count checks, not latency or +ranking-quality measurements. + +Validation on this patch: **124 tests passed**, with the credential-dependent live +test skipped. This includes real local vector/FTS/hybrid searches, async queries, +and TypeSafe SDK 0.7.1 over a mock HTTP transport (including SDK-managed retries). +Repository-wide Ruff formatting/lint, the benchmark CLI, and the MkDocs build +also passed. + +### Live subset test + +A live test on the first 100 cached GooAQ queries (6,851 candidate pairs) passed +with `jev-1.13.0`, SDK 0.7.1, and concurrency 32 in both modes. Candidate IDs, +probabilities, resolved models, and request counts were checked for every record. +All three 80-candidate queries made exactly two batched calls. Live vector, FTS, +hybrid, empty-FTS, and multivector integration checks also passed in both modes. +No correctness fixes were needed. + +The subsequent batch-ordering simplification passed all 124 automated tests and +a fresh four-query live check (original query indices 0, 1, 2, and 8; 292 candidate +pairs). Unbatched/batched calls were 292/8, including exactly two calls for the +80-candidate case. The 100-query measurements below are from the initial +implementation, identified by commit and source hash in the linked report. + +| Batch size | Subset SDK calls | Median | p95 | +| --- | ---: | ---: | ---: | +| 1 | 6,851 | 877 ms | 9,446 ms | +| 40 | 199 | 351 ms | 598 ms | + +| Search | Unbatched Hit@5 / Hit@10 | Batched Hit@5 / Hit@10 | +| --- | ---: | ---: | +| Vector | 82% / 88% | 84% / 89% | +| FTS | 72% / 77% | 73% / 78% | +| Hybrid | 83% / 89% | 84% / 90% | + +These are **subset-test observations, not full benchmark results**. The full run +was manually stopped after 494 matched queries; this summary uses the first 100 +input queries without selection by latency or scores. Counts above exclude other +queries completed before stopping. The high unbatched p95 is retained as observed; +it is not attributed to a specific cause. A complete 2,000-query paired benchmark +is still needed before making a general performance or quality claim. Exact values +and configuration are in [the subset test report](typesafe_subset_test.json). + +The historical GooAQ results motivated this patch: the earlier custom adapter +reported 186 ms median / 387 ms p95; native unbatched scoring at concurrency 32 +reported 805 ms / 1,193 ms for 2,000 queries and 136,586 candidate pairs using +`jev-1.13.0`. Those separate runs are not measurements of this patch. See the +[research results](https://github.com/lancedb/research/blob/codex/use-native-typesafe-reranker/reranking/results/README.md) +and [earlier adapter](https://github.com/lancedb/research/blob/412a522/reranking/jev_reranker.py). + +## Run the paired benchmark + +Use the exact `candidates.json` from the research benchmark cache. It is a JSON +array of records with `query`, expected `answer`, ordered `vector` and `fts` ID +lists, and a `documents` mapping from string IDs to text. Distinct IDs may have +identical text. To prepare candidates without scoring models, use the research +branch's [benchmark](https://github.com/lancedb/research/blob/codex/use-native-typesafe-reranker/reranking/compare_jev.py) +with `--models none`; its default corpus and query counts reproduce the protocol. + +After bootstrapping this checkout's Python development environment, run from +`python/` (set `TYPESAFE_API_KEY` or pass `--api-key-file`): + +```sh +uv run --extra tests --with typesafe-sdk==0.7.1 benchmarks/bench_typesafe.py \ + --candidates /path/to/research/reranking/.benchmark-cache/candidates.json \ + --model jev-1.13.0 --max-concurrency 32 \ + --cache /tmp/typesafe-batching-fresh \ + --output /tmp/typesafe-batching-results.json +``` + +Both modes use the same installed SDK, model, prompt, candidates, and concurrency. +They score each query's candidate union once, alternating which mode runs first. +Timings include native reranking and SDK retries, exclude retrieval, and report +median/p95 milliseconds. Request counts mean logical SDK calls, excluding +SDK-internal retry attempts. The output includes resolved model IDs, package +versions, implementation and candidate hashes, and vector/FTS/hybrid Hit@5 and +Hit@10. As in the research protocol, each metric uses 4× overfetch and a hit means +an exact match to the expected answer text. Ties retain retrieval order. + +Scores and timings can resume from a cache. Cache identities separate batch size, +request format, model, SDK version, concurrency, prompt, implementation, and input +candidate bytes. Use a new cache directory for fresh timings. The report identifies +reused queries; don't compare runs with different resolved models or environments. +API errors and malformed responses abort the benchmark without fallback scores. + +Offline validation from `python/`: + +```sh +uv run --extra tests --with typesafe-sdk==0.7.1 pytest \ + python/tests/test_typesafe_reranker.py \ + python/tests/test_rerankers.py benchmarks/test_bench_typesafe.py -k typesafe -q +``` diff --git a/python/benchmarks/typesafe_subset_test.json b/python/benchmarks/typesafe_subset_test.json new file mode 100644 index 000000000..31966e282 --- /dev/null +++ b/python/benchmarks/typesafe_subset_test.json @@ -0,0 +1,144 @@ +{ + "scope": "Live subset test: first 100 GooAQ queries, not a completed full benchmark.", + "full_benchmark_completed": false, + "source_commit": "ffae20f2acde4720d1ab8d724a66af6afa4a33cc", + "queries": 100, + "candidate_pairs": 6851, + "subset_selection": "First 100 input queries; no selection by scores or latency.", + "request_count_definition": "SDK calls for this subset only; excludes SDK-internal retries and other queries executed before the full run was stopped.", + "live_integrations": [ + "vector", + "FTS", + "hybrid", + "empty FTS", + "multivector" + ], + "results": { + "40": { + "identity": { + "candidates_sha256": "c5744f7a630f5626532f068e92df9a1e6eb34735b379e07df1a3c80d15cbb551", + "model": "jev-1.13.0", + "max_concurrency": 32, + "batch_size": 40, + "request_format": "query-state-structured-document-question-v1", + "instructions": "Does the candidate passage answer the user's query?
