docs: overhaul curation, feature engineering, security and deployment guides (#4748)
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. 🤖 Generated with [Claude Code](https://claude.com/claude-code) https://claude.ai/code/session_018PXMCbRH6i5w47TsjeEUMT --------- Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com> |

fix: preserve all function revisions through SQL history (#4786)
`list_functions()` promises every published immutable revision. Request
`SHOW FUNCTIONS HISTORY` so the SQL server's latest-only default does
not hide older revisions, and preserve the server's numeric revision
ordering when constructing page cursors (`1`, `2`, `10`).
```python
[(fn.name, fn.version) for fn in db.list_functions(page_limit=2)]
# [("embed", "1"), ("embed", "2"), ("embed", "10")]
```
```sql
SHOW FUNCTIONS; -- latest visible revision per name
SHOW FUNCTIONS HISTORY WITH (limit = 3, include_definition = true);
SHOW FUNCTIONS HISTORY WITH (after_name = 'embed', after_version = '2', limit = 3);
```
Each listing page uses the existing SQL query and polling transport; the
continuation token stores the last returned name/revision and remains
bound to its database and namespace. Function mutations keep their
query-backed job handles: `Job.id` is the query's ID and `job_type` is
`query`, so waiting observes that same SQL execution. No registry job or
second query ID is added.
Update the SQL and Python documentation for exact-revision drops:
sibling revisions and grants survive, and only the last visible
revision's removal releases the name and schedules object cleanup.
Extend the existing Flight SQL regression to paginate revisions `1`,
`2`, and `10` and verify the explicit history statement. Formatting and
static Python checks pass; local builds and tests were intentionally not
run.

fix: decode native SQL view metadata (#4785)
View APIs now read the native `name`, `query`, and `schema` columns
returned by `CREATE VIEW` and `DESCRIBE VIEW`. The schema JSON carries
the defining database and namespace; the requested namespace identifies
where the view lives. The unreleased JSON-envelope response is removed
without a compatibility fallback.
```python
view = db.create_view("adults", "SELECT name FROM people WHERE age >= 18")
view = db.describe_view("adults")
```
```sql
CREATE VIEW "adults" AS SELECT name FROM people WHERE age >= 18;
DESCRIBE VIEW "adults";
```
Both Python calls execute SQL through the query-backed job adapter and
wait on the resulting query. A job handle uses that query's `id` and
type `query`; reading metadata consumes its completed result rather than
resubmitting the DDL. Creation returns the definition from the creating
execution, with no extra describe request.

feat: use SQL for remote view lifecycle
Stacked on #4675. Remote view create, describe, list, and drop now execute SQL. CREATE returns the stored definition, resolution defaults, and Arrow schema from the same execution; DESCRIBE VIEW returns that metadata and SHOW VIEWS supports scoped pagination. `drop_view_async()` returns a `job_type="query"` handle whose single `job.id` is the SQL query UUID. Waiting drains the query result once and caches completion; `describe_query(job.id)` works on the submitting connection. Completion means catalog removal, with physical cleanup continuing separately. Query handles have no registry history and cannot be reopened through `open_job()`. |

feat: use SQL for remote function lifecycle
Remote function registration, exact-version lookup, listing, and drop now execute SQL through the Flight client. Registration waits for the durable image build and catalog publication before yielding its typed `FunctionVersion`. SQL also covers source-inclusive description and pinned metadata updates. Registration and drop handles use `job_type="query"`; the single `job.id` is the SQL query UUID and can be inspected with `describe_query()` on the submitting connection. Waiting drains the SQL result once and caches completion for repeated waits. The drop boolean reports catalog removal; physical cleanup continues separately. Query handles have no registry history and cannot be reopened with `open_job()`. |

docs: fix table, accuracy and structure problems found in the pre-launch review (#4745)
## Summary Fixes the problems a page-by-page review of the docs found before launch, after checking each one against the current source and, where noted, the code. The matching fixes for the dataset and Geneva pages, which live in `lancedb/docs`, are in lancedb/docs#402. **Tables** - `integrations/embedding/cohere`: each input-type description was split across two table rows and wrapped in literal quotes (`"`search_document`"`). Now one row per type. - `integrations/embedding/gemini`: removes the same stray quotes from the task-type table. - `integrations/ai/langchain`: the MMR search table's `kwargs` row was missing a cell, so its description sat under Type. - Six reranker pages (answerdotai, cohere, colbert, jina, openai, voyageai): closes the backtick before `_relevance_score`. - `indexing/vector-index`: finishes a cell cut off at "with scalar". - `sql/dql/dedupe`: labels the empty header cell in the resolution table. **Corrections** - `curation/sampling`: sampling works in LanceDB Embedded through the Python SDK, so the page is available in both, with the SQL sections marked Enterprise. - `feature-engineering/index`, `add-computed-column`: automatic refresh is on by default for each computed column and takes effect once a deployment enables its scheduler. `refresh-column` already said so; these two implied it was off. - `indexing/scalar-index`, `indexing/index`: `LABEL_LIST` accelerates `array_has_all`/`array_has_any`; `array_contains_*` doesn't exist. Also merges scalar-index's two "nested fields" sections into one. - `integrations/embedding/ibm`: lists the four current models from `CURRENT_MODELS` (it listed a deprecated one) and explains that the default stays a legacy ID so existing tables reload with their model. - `integrations/reranking/openai`: the class is `OpenaiReranker`, not `OpenAI()`. - `integrations/ai/synthetic-data-kit`: the CLI is `synthetic-data-kit` throughout, each step runs one command, each step passes the file it writes to the next, and `save-as` uses `-f`/`-o`. - `integrations/data/dlt`: `secrets.toml` defines `api_token`, which the pipeline reads, and the run command runs the file the page creates. - `search/vector-search`: the multivector walkthrough connected to Enterprise in step 1 and a local path in step 2. It now runs locally throughout, with a note on connecting to Enterprise, and is renamed so it doesn't read as a duplicate of the short section above. **Structure and wording** - `integrations/embedding/nvidia`: adds headings, and drops test-suite details aimed at contributors. - `integrations/ai/genkit`: makes the retrieval test a real heading and describes the query step. - `integrations/data/voxel51`: replaces a raw MkDocs `!!! note` with a `<Note>`. - `sql/ddl/table`, `sql/ddl/job`: "Errors and limits" is a real heading, not bold text. - `curation/windowing`: sidebar title matches the curation overview ("Rank and Deduplicate"). - `deployment/storage`, `basics/agentic-skills`: fixes a garbled sentence and a stale reference to the quickstart. **Checked:** no new Vale alerts on the changed pages. Assembled together with lancedb/docs#402, the site passes `mint validate` and `mint broken-links --check-anchors --check-redirects`. Every changed page was reviewed in a local preview. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com> |

docs: complete SQL reference, enrich Functions drafts, rename OSS to Embedded (#4732)
## 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. |

feat: configure automatic refresh when declaring computed columns (#4607)
Add `auto_refresh_enabled` and `auto_refresh_interval_seconds` to the
Rust builder and Python sync/async add-column APIs for computed columns
and registered Function outputs.
Python users can configure refresh when declaring a column:
```python
table.add_columns(
computed={"total": "price * quantity"},
auto_refresh_enabled=True,
auto_refresh_interval_seconds=300,
)
```
Omit the interval to let the server determine when to refresh:
```python
table.add_columns(computed={"discounted_total": "total * 0.9"})
```
The async API accepts the same options:
```python
await async_table.add_columns(
computed={"total": "price * quantity"},
auto_refresh_enabled=True,
auto_refresh_interval_seconds=300,
)
```
For an existing registered `FunctionApplication`, the options also apply
to Function columns. Disabling automatic refresh still permits explicit
refresh:
```python
table.add_columns(
{"features": function_application},
auto_refresh_enabled=False,
auto_refresh_interval_seconds=300,
)
table.refresh_column("features")
```
Options apply to every output declared by a call. Automatic refresh is
enabled by default; when the interval is omitted, the server determines
when to refresh. An explicit interval sets a minimum delay after a
successful refresh. The interval does not force recomputation of
unchanged inputs. Invalid intervals and options on one-time transforms
are rejected before declaration.
Native declarations persist `computed_column.auto_refresh_enabled` and
an explicitly supplied `computed_column.auto_refresh_interval_seconds`
in each output field’s metadata in the same commit as the declaration.
An omitted interval is neither stored nor sent in remote requests.
Remote declarations forward the settings to Cloud/Enterprise servers.
Local tables store these settings; automatic execution requires a
supporting server with scheduling enabled.

docs: add realtime engine (RTE) getting-started guide (#4548)
Adds a user-facing realtime engine (RTE) page at `docs/web/tables/realtime-engine.mdx`, listed under **Management** after Branches. It is adapted from the internal WAL field guide (lancedb/sophon#6213), with the deployment and operations material left out. The page covers: - what RTE is and how it works (memtable → SSTables → compaction; reads merge the base table with the fresh tier) - getting started: `set_unenforced_primary_key`, indexes, `enable_rte` / `ALTER TABLE ... SET RTE`, `merge_insert` upserts and queries, partial updates, deletes, and `checkpoint_rte` / `disable_rte` - performance: write throughput and shard scaling, and read latency with and without RTE - a note on operations not yet supported (time travel, branching, `count_rows`, row IDs, `TABLESAMPLE`) Also aligns related docs with current RTE naming and behavior: - `sql/ddl/table.mdx`: `SET MEMWAL` / `UNSET MEMWAL` → `SET RTE` / `UNSET RTE` - `maintenance/background-jobs.mdx`: job names are `memwal_compaction` and `memwal_catchup_<type>` - `feature-engineering/materialized-views.mdx`: MemWAL → realtime engine - Python `AsyncTable.enable_rte` / `RTEWriteSpec.with_maintained_indexes` docstrings: by default, indexes created after enabling RTE are maintained too The examples are written directly in the page rather than generated from `docs/web-tests`, because RTE needs an Enterprise server to run. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Co-authored-by: XY Zhan <zhaner08@hotmail.com> |

docs: clean up prose flagged by the shared Vale rules (#4596)
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. |

refactor!: rename LSM APIs to MemWAL and align SSTable/table shard naming (#4075)
## What Renames the MemWAL surface in two passes, across Rust, Python, TypeScript, and Java, including the wire format. ### 1. MemWAL APIs drop "LSM" The write path these APIs drive is Lance's MemWAL; "LSM" described its shape rather than naming it. Turning it on and off now reads as enabling a feature rather than installing a spec. | Before | After | |---|---| | `set_lsm_write_spec` | `enable_memwal` | | `unset_lsm_write_spec` | `disable_memwal` | | `get_lsm_write_spec` | `get_memwal_spec` | | `flush_lsm` / `compact_lsm` / `checkpoint_lsm` | `flush_memwal` / `compact_memwal` / `checkpoint_memwal` | | `get_lsm_stats` | `get_memwal_stats` | | `close_lsm_writers` | `close_memwal_writers` | | `use_lsm` (query, merge insert) | `use_memwal` | | `LsmWriteSpec` / `LsmStats` | `MemWalWriteSpec` / `MemWalStats` | | Java `LanceDbTableLsm` | `LanceDbTableMemWal` | TypeScript and Java use camelCase (`enableMemWal`, `getMemWalStats`, ...); the napi methods set `js_name` so the generated names keep the `MemWal` casing. flush/compact/checkpoint keep a `_memwal` suffix so `compact_memwal` is not confused with `compact_files` / `optimize`, which compact the base table. Internal names (`LsmMode`, `LsmScanner`, the `merge::lsm` / `query::lsm` modules) are unchanged. ### 2. Stats use SSTable and table shard Aligns the stats surface with the MemWAL naming settled upstream in lance-format/lance#7943 and #7957, where the persisted unit became an **SSTable**. **Generation → SSTable.** A `GenerationStats` describes one flushed MemTable, which is an SSTable. The generation *number* is kept — an SSTable is identified by its generation — so only the noun moved. **Bucket → table shard.** Each entry is one MemWAL shard. "Bucket" names only the hash sharding *transform*, so it was already wrong for `identity` and `year` sharding, which produce shards and no buckets at all. | Before | After | |---|---| | `GenerationStats` | `SsTableStats` | | `BucketStats` | `TableShardStats` | | `stats.buckets` | `stats.table_shards` | | `BucketStats.generations` | `TableShardStats.sstables` | | `include_generation_rows` | `include_sstable_rows` | | `newest_generation` | `newest_sstable_generation` | | `outstanding_generations` | `outstanding_sstables` | Docs and comments follow suit: "seal" → "freeze", "L0" / "flushed generations" → SSTables, "bucket" (meaning a shard) → table shard. `MemWalWriteSpec::bucket`, `num_buckets`, and the `"Sealed"` shard status value are **unchanged** — those name the sharding transform or a server value, not the shard. ## Compatibility Breaking, for an experimental API. The wire format changes with the SDKs, so this must roll out together with the matching server change: - Routes: `/set_lsm_write_spec/` → `/enable_memwal/`, `/unset_lsm_write_spec/` → `/disable_memwal/`, `/get_lsm_write_spec/` → `/get_memwal_spec/`, `/flush_lsm/` → `/flush_memwal/`, `/compact_lsm/` → `/compact_memwal/`, `/get_lsm_stats/` → `/get_memwal_stats/` - Response keys: `lsm_write_spec` → `memwal_spec`, `lsm_stats` → `memwal_stats`, `buckets` → `table_shards`, `generations` → `sstables` - Request fields: `include_generation_rows` → `include_sstable_rows`; `use_lsm` → `use_memwal` on query and merge-insert bodies ## Validation - Rust: `cargo test --features remote -p lancedb --lib --tests` — 1467 lib tests and all integration test targets pass; `cargo clippy` clean - Python: rebuilt the extension; `test_remote_db`, `test_memwal_spec`, `test_merge_insert_lsm`, `test_query`, `test_permutation`, `test_table` — 655 passed; `ruff format` / `ruff check` clean - TypeScript: `pnpm build`; `table`, `merge`, `query` tests — 593 passed; `biome check` clean; `docs/src/js` regenerated with `npm run docs` - Java: `mvn test` — 37 passed (Spotless applied with JDK 11; the pinned google-java-format does not run on JDK 21) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com> |

docs: correct data workflows, SQL and operations (#4534)
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`. |

docs: bring the open-source documentation into this repository (#4122)
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.
