::: lancedb.materialized_view.VectorDedupSource
For an existing indexed source, declare and materialize a dedup result without
writing SQL. Creation captures the source version once and waits for the complete
result; remote connections use the service's MV jobs.
```python
from lancedb import vector_dedup
view = db.create_materialized_view(
"images_clean",
vector_dedup("images", column="phash", distance_threshold=4),
)
cleaned = view.table
```
To submit without waiting, call `db.create_materialized_view_async(...)` with the
same source expression and wait on the returned job. To declare only, pass
`with_no_data=True`, then use `view.refresh_async().wait()` when ready. Pass
`dataset_version=...` to `vector_dedup` for an explicit snapshot. The default
policy retains direct representatives (A-B-C without A-C keeps A and C), preserves
the source, and materializes its original columns. Only within-segment/partition
pairs are covered, using the index's distance representation.

## 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

"""WAL-PK-FUSION: hybrid search's primary-key fallback for MemWAL tables.
Hybrid search joins its vector and full-text legs on `_rowid`, which a MemWAL
table cannot supply: the fresh tier has no stable row id, so the server rejects
`with_row_id` before it plans. When that happens the legs are joined on a
surrogate `_rowid` built from the table's primary key instead.
This is a stopgap until MemWAL supports `_rowid`, and everything it needs lives
here so it can be removed in one pass:
1. Delete this file and `tests/test_wal_hybrid.py`.
2. Run `grep -rn WAL-PK-FUSION python/ rust/` and follow the note at each
marker; the Rust side has its own copy in
`rust/lancedb/src/query/wal_fusion.rs`.

Only same-segment/same-IVF-partition pairs are considered; quantized distances

``source`` is an exact table name in the connection's root namespace, just
as for ``create_materialized_view``. ``dataset_version=None`` captures the
source's version when creation is submitted. Pass an explicit positive

source columns and rows. Do not combine this source with ``select``,
``where`` or ``limit``; query the resulting table for further transforms.
Creation follows the usual MV contract: by default it waits for the result.

execution uses server-side MV registry jobs; local connections run in process.
