Subject: [PATCH 1/6] feat: return a cleanup job from drop_view (#4262)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dropping a view unbinds its name and leaves the definition dataset to a
server-side cleanup job, so the two are separate events a caller may
want to wait on.

`drop_view_async` returns that job — the same shape
`drop_materialized_view_async` and `drop_function_async` already use: a
`202` carries the job id, a `200` (nothing was bound to the name) yields
an already-finished job with no id, and any other success status is an
error rather than a silent no-op.

## `drop_view` waits

`drop_view` now awaits the job before returning, so a caller who does
not want to think about cleanup gets the stronger guarantee: when it
returns, the definition really is deleted.

That is deliberately **different** from `drop_materialized_view` and
`drop_function`, which return as soon as the name is unbound and
document that content may still be deleting. The view API is the newer
one, and waiting is the semantic worth having; the other two are left
alone rather than changing behaviour already released.

## Surfaces

`Database` trait, the remote client, `Connection`, and the Python and
Node bindings — matching where `drop_materialized_view_async` is already
exposed.

Four client tests cover the accepted case reporting its job id, the
nothing-bound case reporting a finished job, a `202` without a usable
`job_id`, and an unexpected success status.

Subject: [PATCH 3/6] feat(python): add opt-in request batching to
 TypeSafeReranker (#4316)

Adds opt-in `batch_size=40`: 80 non-null candidates use **2 requests
instead of 80**. 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).

 ## Reranking
 
+`TypeSafeReranker` supports opt-in request batching:
+
+```python
+from lancedb.rerankers import TypeSafeReranker
+
+reranker = TypeSafeReranker(batch_size=40, max_concurrency=8)
+```
+
+The default `batch_size=1` keeps the query and document in request state and
+sends one request per non-null candidate. With `batch_size=40`, 80 non-null
+candidates require two requests. `max_concurrency` still limits simultaneous
+requests, and the SDK handles retries.
+
+In batched mode, state contains only `{"query": query}`. Each independent
+question contains `{"question": instructions, "document": document}` in its
+structured instructions, so it sees only its own document and the shared query.
+Custom instructions and criteria are kept verbatim: adapt prompts that explicitly
+reference request-state fields such as `state.document` before enabling batching.
+Null documents retain a zero score without an API call; empty strings are scored.
+API failures, mismatched answer IDs, and invalid probabilities raise errors.
+Batching changes the payload and can affect model scores; compare quality and
+latency on your workload before opting in.

+# TypeSafe request batching
+
+## Available evidence
+
+The focused tests exercise the native reranker with a mocked API. For 80 non-null
+candidates, `batch_size=1` makes 80 `system_one` calls and `batch_size=40` makes
+exactly two. 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

Subject: [PATCH 4/6] 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.

From 604b1b583b3a5aad4f64f822ab1fe06c8666d910 Mon Sep 17 00:00:00 2001

Subject: [PATCH 6/6] feat: pause and resume jobs from the Python SDK (#4112)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Cancellation is the only job control the SDK exposes, and it is
terminal, so a long-running server-side job cannot be parked and picked
up again. This adds `pause_job` and `resume_job` to the Rust core
connection and the Python bindings (sync and async), posting to the
server's `/v1/jobs/pause` and `/v1/jobs/resume` endpoints.

A pause parks the job until it is resumed: its workers drain and stop.
The outcome strings mirror the server's answers — a job finalizing its
results reports `"committing"` and cannot be parked, and a resume before
the drain is confirmed reports `"still_pausing"`; both are retried
rather than failed. Resuming re-queues the job and its workers pick
their work back up from checkpoints. Local connections report the
operations as unsupported, like the rest of the jobs API.
