rejected now rather than at the first read. A view holds no rows, and its
readers see its sources as they are at read time.

[@lancedb/lancedb](../globals.md) / OAuthSession
# Class: OAuthSession
Explicit OAuth session lifecycle for the persistent token cache: eager
`login`, non-secret `status`, and local `logout`.
A session is built from the same [OAuthConfig](../interfaces/OAuthConfig.md) used to connect
(including its `tokenCache` options). A connection created with the same
configuration shares the cache, so logging in here prepares tokens for
later processes without any database request.
`login` always runs the configured interactive flow and replaces the cached
session (the most recent login wins). `logout` removes only the local
credential; it does not revoke anything with the provider and does not sign
out of a browser SSO session.
## Example
```typescript
const config: OAuthConfig = {
issuerUrl: "https://issuer.example.com",
clientId: "my-app",
scopes: ["openid", "offline_access"],
flow: OAuthFlowType.DeviceCode,
tokenCache: { cacheDir: "/tmp/my-app/oauth-cache" },
};
const session = new OAuthSession(config);
const status = await session.login();
```
## Constructors
### new OAuthSession()
```ts
new OAuthSession(config): OAuthSession
```
Create a session manager for the given OAuth configuration.
#### Parameters
* **config**: [`OAuthConfig`](../interfaces/OAuthConfig.md)
#### Returns
[`OAuthSession`](OAuthSession.md)
## Methods
### login()
```ts
login(): Promise<SessionStatus>
```
Eagerly run the configured authentication flow and store the session.
A successful login always replaces any prior cached session for this
identity; if the provider does not issue a refresh token (for example
without `offline_access`), the previous record is removed and the status
reports `refreshable == false`.
#### Returns
`Promise`&lt;[`SessionStatus`](../interfaces/SessionStatus.md)&gt;
***
### logout()
```ts
logout(): Promise<SessionLogout>
```
Remove the matching local cached credential.
This only deletes the local cache entry. It does not revoke the refresh
token with the provider and does not sign out of a browser SSO session.
Repeated calls succeed; `removed` reports whether a credential existed.
#### Returns
`Promise`&lt;[`SessionLogout`](../interfaces/SessionLogout.md)&gt;
***
### status()
```ts
status(): Promise<SessionStatus>
```
Report whether a matching cached session exists, with safe metadata.
This never contacts the identity provider and never exposes token values.
#### Returns

### functionErrors()
```ts
abstract functionErrors(options?): Promise<FunctionErrors>
```
The per-row errors Function refreshes recorded on this table.
A refresh running under a skip policy records each row it skipped with
the input that failed and the error. This lists those records, newest
job first, plus a summary for any fragment whose per-row detail was
capped. LanceDB Cloud and Enterprise only; reading errors needs read
access to the table, since a message carries the value that failed.
#### Parameters
* **options?**: [`FunctionErrorsOptions`](../interfaces/FunctionErrorsOptions.md)
Optional filters: `jobId`,
`column`, and `limit` (server default 10000, cap 100000).
#### Returns

Options for the persistent OAuth token cache.
The cache is opt-in: it is only used when set as `tokenCache` on

directory with owner-only permissions, so short-lived processes can reuse

`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:

recommendation and the default configuration of Okta confidential
applications; without a secret the client is public and no client
authentication is sent.
redirect_uri : Optional[str]
Loopback redirect URI for AUTHORIZATION_CODE. The default is
``http://127.0.0.1:{callback_port}/callback``.
callback_port : Optional[int]
Port for the AUTHORIZATION_CODE loopback callback server (default: 8400).
use_pkce : bool
Protect AUTHORIZATION_CODE with S256 PKCE (default: True).
managed_identity_client_id : Optional[str]
Client ID for user-assigned managed identity (AZURE_MANAGED_IDENTITY).
resource : Optional[str]
Resource indicator (RFC 8707), forwarded verbatim to authorization and
token endpoints, including refresh requests. Must be an absolute URI
without a fragment. Not supported for Azure managed identity.
audience : Optional[str]
Provider-specific audience, forwarded to authorization and token
endpoints, including refresh requests. Not supported for Azure managed identity.
refresh_buffer_secs : Optional[int]
Seconds before expiry to trigger proactive refresh (default: 300).
Keep this well below the token TTL; if it is greater than or equal to
the TTL, each request refreshes the token.
token_cache : Optional[TokenCacheOptions]
Opt in to the persistent token cache so short-lived processes reuse
one session. Only supported by AUTHORIZATION_CODE and DEVICE_CODE;
azure managed identity is rejected. Default: None (memory only).

class TypeSafeReranker(Reranker):
"""
Reranks the results using the TypeSafe System One API.
https://docs.typesafe.ai/cookbooks/rerank_typesafe
Each result is scored independently: TypeSafe reads the query together with
the result's ``column`` value and answers a yes/no ("noul") question about
whether the document is relevant. The probability of "yes", between 0 and 1,
becomes the ``_relevance_score``. Because every score is an absolute
probability rather than a position in the list, scores are comparable
across queries and can be thresholded. They are model estimates, though,
and can vary slightly between identical calls, so results with close scores
may swap places when the same search is repeated.
By default, one request is sent per non-null result. Set ``batch_size=40``
to score up to 40 documents per request, with at most ``max_concurrency``
requests in flight. Each question sees only its own document and the shared
query. Null documents keep a score of zero without an API request; empty
strings are scored normally. API and response-validation errors propagate.
Parameters
----------
model_name : str, default "jev-latest"
The TypeSafe model to use.
column : str, default "text"
The name of the column holding the document text to score.
instructions : str, optional
The yes/no question asked about each query and document pair. The state
TypeSafe reads with ``batch_size=1`` is
``{"query": <query>, "document": <column value>}``.
Defaults to a generic relevance question. See ``batch_size`` for the
different location of the document in batched requests.
criteria : Mapping[str, str], optional
What a "yes" and a "no" mean, as a mapping with the keys ``"true"`` and
``"false"``. Domain-specific criteria usually rank better than the
generic default. Pass an empty mapping to send no criteria.
return_score : str, default "relevance"
Options are "relevance" or "all". If "all", keeps the vector and FTS
scores alongside the relevance score.
api_key : str, optional
The API key to use. If None, the TypeSafe SDK reads the
``TYPESAFE_API_KEY`` environment variable.
max_concurrency : int, default 8
The maximum number of TypeSafe requests in flight for one rerank call.
batch_size : int, default 1
Positive integer limiting non-null documents per request. The default
preserves the original request format. With a value greater than one,
state is ``{"query": <query>}`` and each question's instructions are
``{"question": <instructions>, "document": <column value>}``.
Instructions and criteria are preserved verbatim. Custom prompts that
explicitly reference the document in request state (for example,
``state.document``) must be adapted before opting into batching.
The TypeSafe SDK handles retries in both modes.
