Expose aggregate CPU, memory, and GPU budgets plus GPU-class placement
on materialized-view refreshes in Python and Rust. Forward options
through SQL and reject invalid or unsupported Embedded requests instead
of silently dropping constraints.
```python
job = view.refresh_async(
cpu_millis=8000,
memory_bytes=16 * 1024**3,
gpu_count=2,
gpu_class="h100",
)
job.wait()
```
```sql
REFRESH MATERIALIZED VIEW curated_training_set
WITH (cpu_millis = 8000, memory_bytes = 17179869184,
gpu_count = 2, gpu_class = 'h100');
```
The same options apply to blocking refreshes, async Python connections,
and the Rust refresh builder. CPU/memory budgets require all three
resource fields; GPU-only caps and class-only placement are also
supported. These are execution-wide caps and require a supporting
Enterprise server with an isolated execution backend. A cap does not
increase refresh parallelism; current MV refreshes use at most one GPU.
Updates API documentation and SQL reference, with Python sync/async and
Rust remote-submission regression coverage. Formatting and Python lint
pass; local builds and tests are intentionally skipped.
The Linux CI build and example steps explicitly select the LanceDB
package, matching the feature-test step. This avoids rebuilding and
retaining a second dependency graph after a workspace-wide build, which
exhausted runner disk space on both this branch and main.
Related: [ENT-3386](https://linear.app/lancedb/issue/ENT-3386)
Adds Python where= examples next to the SQL ones.
Also fixes two examples that fail:
- Date filters now use date '2026-01-01'. A bare string fails on DATE
and TIMESTAMP columns (see [Dates, Timestamps,
Decimals](https://docs.lancedb.com/search/filtering#dates-timestamps-decimals)).
- The first example reads results with table.search().to_arrow(),
because table.to_arrow() raises on Enterprise.
where= needs lancedb 0.42.0 or later.
The refresh guide and SQL reference do not warn that a `WHERE` refresh
recomputes filled rows, and the guide describes resources as per-worker
allocations. Clarify the aggregate Function budget and expression-only
`num_workers`, show the output-null predicate with its stale-value and
successful-null limitations in both references, and document
refresh-level `error_policy='skip'`. Link both guides to the current SQL
options route.
Validation: Vale 3.24.0 found no issues on changed lines; `git diff
--check` and the new link targets passed. Mint 4.2.888 reports the same
four existing `RsExampleBody`/`RsExampleTail` import warnings in
`reranking/index.mdx` and `search/vector-search.mdx` on both pristine
base `5e38120b` and this branch. No additional warnings. Behavior was
checked against the owning Sophon implementation; no runtime code
changed or runtime tests were run.
Companion to https://github.com/lancedb/sophon/pull/9806 for ENT-3279.
Page visibility and saved documentation editions are unchanged. DOC-90
retains publication and matching-shipped-release verification.
A broad documentation pass across the areas LanceDB Enterprise and
Embedded
diverge on most:
**Data Curation** -- GPU Function execution, Slurm scheduling (and what
Slurm is, for readers new to it), blob late materialization as its own
page, joins, aggregation/profiling, sampling, near-duplicate detection,
chunking, distributed shuffle, and IVF-partition clustering.
**Feature Engineering** -- computed columns and materialized views,
restructured to lead with the Function-based path and show the SQL form
side by side with Python throughout; a single Auto Refresh page instead
of
duplicating scheduling details on every refresh page; adaptive
execution;
checkpointing; GPU and Slurm placement for refresh workers; a Training
Cache page for the PyTorch data loader's automatic cache benefit.
**Security & Governance** -- an Audit Log reference (schema, access,
grants), Secrets promoted to an ordinary catalog object with their own
SQL
DDL and a vending/rotation guide, and privilege-table fixes verified
against the authorization source.
**Deployment & Maintenance** -- Horizontal Scaling and OpenTelemetry
moved
into a real Deployment area; Automated Cleanup folded into Intelligent
Auto-Maintenance (every other maintenance decision already lived there);
RTE Compaction and Advanced Conflict Resolution documented in depth.
**Landing page** -- the Enterprise feature comparison table reorganized
(several redundant or stale rows removed, several new areas added), and
the
"why Enterprise" bullets replaced with ones tied to a concrete page
(Performance, Scale, Fault tolerance, Multicloud deployment, Simplify
operations) instead of vague promises.
Plus a full pass addressing lancedb-gatekeeper's review: a real
test-safety
bug (a quickstart test could silently overwrite and delete a
deployment's
own `frames` table), a fabricated SQL statement with no backing
implementation, an actual dedup-guarantee bug in `take_row_ids`, and
dozens
of documentation-accuracy fixes verified against source rather than
taken
on faith -- each either fixed, or left with an explicit note on why it
needs a feature or deployment owner's sign-off instead of being guessed
at.

## Summary
- Complete the SQL reference: `ATTACH DATABASE`, the `CHANGES` clause,
and
`dedupe()`/`duplicate_pairs()` (verified against current sophon source;
these were recently renamed from
`vector_dedup`/`vector_duplicate_pairs`).
Fix the blob-column default-projection claim and add the previously
undocumented `blob_descriptor()`.
- Enrich the gated Functions draft (still `.mintignore`'d, pre-release):
chained Functions over blob outputs, GPU-produced blobs, Secrets,
multi-input/output binding, `code=[module]` packaging.
- Upgrade the materialized-view and computed-column auto-refresh drafts
with
precise, verified catch-up semantics, and add the missing `ALTER
MATERIALIZED VIEW` / `CREATE ... WITH(...)` sections (also gated — the
automatic-refresh scheduler is still dev/staging-only).
- Thread one running example (video frames → GPU extract/caption → dedup
→
auto-refreshing materialized view) through Functions, materialized
views,
and the LeRobotDataset integration guide instead of a separate tutorial.
- Rename "LanceDB OSS"/"OSS" to "LanceDB Embedded"/"Embedded" throughout
(52 files); activate the existing availability-comparison mechanism on
`basics/offerings.mdx` for a full feature-by-feature comparison table.
The existing docs have 254 findings from our shared Vale rules.
Contributors would otherwise inherit these when editing the same lines.
Clean up the prose across 80 pages: correct product names and a repeated
word, simplify a few phrases, and replace dashes with punctuation that
fits each sentence. The pinned Vale scan now reports zero findings, with
no suppressions.
This PR is part of the documentation revamp. Once the full set of PRs is
merged, we’ll publish the combined site to staging for review before
updating docs.lancedb.com.
The curation, SQL and operations pages contain outdated claims and
examples that do not reliably work as written.
This corrects those pages against the reviewed SDK and local server
evidence, including prepared statements, background jobs, cleanup and
monitoring. Integration guides are grouped with their examples in #4533.
Function and Secret-object documentation stays unpublished until its
release. The two Function pages are listed in `.mintignore` and left out
of the navigation, and the sections about them on other pages are MDX
comments.
Stacked on #4533. Each MDX file has one PR owner. Rebase onto main after
#4533 is squash-merged.
Local assembly, Mint validation and link checks pass, and the assembled
site shows no Function or Secret-object content. A local release
rehearsal that uncomments the drafts and restores the navigation also
passes. Hold publication until this PR and lancedb/sophon#8688 are on
`main`.
Move the public website pages into `docs/web` beside the SDK, with
shared navigation and executable example sources in `docs/web-tests`.
The combined website is assembled by
[lancedb/docs#355](https://github.com/lancedb/docs/pull/355), with six
Enterprise replacements from
[lancedb/sophon#7681](https://github.com/lancedb/sophon/pull/7681).
This includes Function guidance, runnable Quickstarts, regenerated
snippets, production contact/demo fixes, the legacy SQL route, and the
LeRobot redirect. LeRobot remains attributed to Geneva; all 34 Geneva
pages remain in the docs repository until Function officially launches.
Materialized-view guidance follows the full rebuild refresh introduced
by #4373: local refresh writes the complete result, has no `full`
argument, supports `source_version`, and no longer requires stable row
IDs. Deployment SQL refresh options and stable-ID setup are qualified by
version/configuration. Function input guidance distinguishes ordinary
stored columns from computed inputs supported by newer deployments.
**Validation:** independently accepted local checks include 95 Python
tests (real Enterprise excluded), eight TypeScript tests, Rust
Quickstart, snippet parity, typos, deterministic assembly, Mint
validation and links/anchors/redirects. The combined baseline retains
all 181 production routes and 17 legacy redirects. Examples ran locally
against source-built Python SDK 0.40.0b13; existing GitHub workflows do
not run `docs/web-tests`. New main at `069b2f7d` is 0.41.0b0 and adds
computed Function inputs; that SDK was not exercised by the accepted
tests. Latest prose corrections receive focused site validation.
**Merge/rollout:** merge this and #7681 before #355's combined CI, which
reads producer `main`. This is migration infrastructure: section
overlays, source-owned skills and automatic versioned paired releases
remain follow-ups. The current manual publisher is transitional. Hosted
validation, a supported SDK/Enterprise release pair and a real
Enterprise walkthrough remain pending.
Production Mintlify watches `lancedb/docs:deploy-freeze`, directory
`docs`; preserve that source through review. The separate SDK GitHub
Pages reference workflow rebuilds on main merges.
**Updated-head CI (9a50f8db):**
[Typos](https://github.com/lancedb/lancedb/actions/runs/37654185443/job/112904990558),
[PR
title](https://github.com/lancedb/lancedb/actions/runs/37654179507/job/112904974595)
and
[Aikido](https://app.aikido.dev/featurebranch/scan/215386145?groupId=74229)
pass. Critical findings in the example lockfiles were patched: all Sharp
copies use 0.35.5, protobufjs 7.6.6, tar 7.5.22, quinn-proto 0.11.19,
zerovec 0.11.8 and zerovec-derive 0.11.6. The SDK's product dependencies
are unchanged. The revised lockfiles pass eight TypeScript examples,
HuggingFace decode/resize/crop/rescale/normalize plus AVIF roundtrip,
and Rust Quickstart. Aikido passing does not mean every advisory is
cleared; npm still reports 29 high and five moderate advisories in the
example dependency graph. No scanner bypass or suppression was added.
The Function prose correction passes combined/standalone Mint,
deterministic assembly, routes and assets. The revised 325-file site
checksum is
`175bec06864abb400dd292e667ba93448c0479b8359fd7bf6146afabf9040647`. This
PR remains open for independent review; further merges are on hold.
