Default `batch_size=1` preserves the existing payload. Each batched question sees only its document and the shared query; instructions/criteria stay unchanged. Prompts referencing `state.document` need adaptation. Concurrency still limits requests; retries remain SDK-managed. Batch-local IDs and ordered results preserve duplicate documents; invalid IDs/probabilities raise without fallback. Validation: **124 automated tests passed**, plus live search integrations in both modes. A **100-query live subset test of the initial implementation** (6,851 candidate pairs; `jev-1.13.0`, SDK 0.7.1, concurrency 32) passed: unbatched/batched calls **6,851/199**, median **877/351 ms**, p95 **9,446/598 ms**. Hybrid Hit@5/Hit@10 was **83%/89% vs 84%/90%**; vector/FTS results and exact configuration are in the [test report](https://github.com/lancedb/lancedb/blob/typesafe-request-batching/python/benchmarks/typesafe_batching.md). Ruff and MkDocs passed. The simplified batching flow also passed a fresh four-query live check: 292 candidate pairs, with 292 unbatched versus 8 batched calls. Builds on #4209; motivated by [research #7](https://github.com/lancedb/research/pull/7). --- docs/src/python/python.md | 23 ++ python/benchmarks/bench_typesafe.py | 245 +++++++++++++ python/benchmarks/test_bench_typesafe.py | 109 ++++++ python/benchmarks/typesafe_batching.md | 99 +++++ python/benchmarks/typesafe_subset_test.json | 144 ++++++++ python/python/lancedb/rerankers/typesafe.py | 99 ++++- python/python/tests/test_rerankers.py | 39 +- python/python/tests/test_typesafe_reranker.py | 338 ++++++++++++++++++ 8 files changed, 1070 insertions(+), 26 deletions(-) create mode 100644 python/benchmarks/bench_typesafe.py create mode 100644 python/benchmarks/test_bench_typesafe.py create mode 100644 python/benchmarks/typesafe_batching.md create mode 100644 python/benchmarks/typesafe_subset_test.json create mode 100644 python/python/tests/test_typesafe_reranker.py diff --git a/docs/src/python/python.md b/docs/src/python/python.md index 68cd306c4..ccc44a55e 100644 --- a/docs/src/python/python.md +++ b/docs/src/python/python.md @@ -379,6 +379,29 @@ still work.

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?

From: Xuanwo Date: Thu, 24 Sep 2026 18:02:25 +0800 Subject: [PATCH 3/4] fix(python): warn instead of failing on local imports in @udf source (#4318) Since 0.40.0b8 (#4254), `@udf` raises when the packaged source imports a module from a local source tree that is neither shipped with `code=` nor named by a declared pip/conda package. That turned registrations that used to succeed into errors: - Callers that rewrite the packaged source before registering it now fail at decoration. Sophon's datagen integration suite inlines its test-module helpers this way, and `test_registered_udf_source_stands_alone_on_a_worker` fails on 0.40.0b8. - The check cannot know which modules a distribution installs. A declared package whose distribution name differs from its module (for example an internal library installed editable) is reported as local, and there was no way to proceed. This keeps the diagnosis but makes it a `UserWarning`, so registration behaves as it did before #4254 and still tells the author, at registration time, why the worker is likely to fail. --- python/python/lancedb/functions.py | 25 +++++++++++++------ .../python/tests/test_function_packaging.py | 18 ++++++++----- 2 files changed, 29 insertions(+), 14 deletions(-) diff --git a/python/python/lancedb/functions.py b/python/python/lancedb/functions.py index 380625f57..5f26b590e 100644 --- a/python/python/lancedb/functions.py +++ b/python/python/lancedb/functions.py @@ -26,6 +26,7 @@ import re import sys import textwrap import types +import warnings from collections.abc import Mapping, Sequence from datetime import date, datetime from typing import ( @@ -1527,9 +1528,14 @@ class _SourcePackager: return f"{name} = {_literal_source(value)}" def _require_importable(self, module_name: str) -> None: - """Refuse an import the Function's environment has no way to satisfy: - a module that lives in a local source tree, is not shipped with - ``code=``, and names no declared package.""" + """Warn about an import the Function's environment likely cannot + satisfy: a module that lives in a local source tree, is not shipped + with ``code=``, and names no declared package. + + A warning rather than an error: a distribution name need not match + the module it installs, so a declared package can still provide the + module, and callers may rewrite the packaged source before + registering it.""" top = module_name.partition(".")[0] if ( top in self._code_modules @@ -1543,10 +1549,12 @@ class _SourcePackager: roots = _installed_roots() if not locations or any(location.startswith(roots) for location in locations): return - raise ValueError( + warnings.warn( f"@udf source imports {module_name!r} from {locations[0]}, a local " - "module the Function's environment cannot import; ship it with " - f"code=[{top}] or declare the package that provides it in pip/conda" + "module the Function's environment may not be able to import; ship " + f"it with code=[{top}] or declare the package that provides it in " + "pip/conda", + UserWarning, ) @@ -1991,8 +1999,9 @@ def udf( place.
