python: create_index returns Job / AsyncJob (ENT-1966)

Table.create_index, create_scalar_index, create_fts_index, and the
materialized-view delegates now return a Job (AsyncJob on AsyncTable).
When the server defers the build (pending vector index), the returned
job tracks it through the platform jobs API; synchronous builds (scalar,
FTS, native tables, GPU-accelerated local paths) return a pre-completed
job whose status()/wait() report finished immediately and whose cancel()
is a no-op. AsyncTable now carries its owning connection so the async
handles can reach the jobs API. wait_timeout keeps working; docs steer
new code to job.wait().

-## Connecting to the LanceDB remote server
-
-LanceDB Enterprise/Cloud deployments are served by a server implementing the lance-namespace OpenAPI spec (<https://github.com/lance-format/lance-namespace/blob/main/docs/src/spec.yaml>). Every remote (`db://...`) connection talks to such a server, and some operations exist only there. In particular, **all operations around jobs (listing, inspecting, creating, or canceling jobs) run server-side** — there is no local/OSS equivalent. Before any job work, or any direct REST call to an Enterprise deployment, read `references/remote_connect.md` to resolve the base URL, credentials, and database header and to validate the connection. Then use the four job REST methods documented in `references/remote_jobs.md` (list, describe, cancel, query_events).

-## Merging a branch into main (Enterprise only)
-
-Merge is available through the SDKs (`table.branches.merge(...)`) on **Enterprise tables only** — it is not supported on Cloud or local/OSS tables, which raise `NotSupported`.
-
-`merge` takes the branch to merge **from** and a `dry_run` flag. Both the SDK method and the underlying REST endpoint **actually merge by default** (`dry_run=False`); pass `dry_run=True` to only preview. A rejected merge is **not an exception** — it returns a result with `status="rejected"` rather than raising, so inspect the return value. Use `branches.diff(from_branch)` to inspect a branch's pending diff without attempting a merge.
-
-```python
-exp = "experiment-reindex"
-
-# preview only — returns status="ready" if it would merge cleanly
-preview = table.branches.merge(exp, dry_run=True)
-
-# actually merge (default)
-result = table.branches.merge(exp)
-if result["status"] == "merged":
-    print("landed at", result["mainVersionAfter"])
-elif result["status"] == "rejected":
-    print(result["diff"]["mergeBlockers"])   # why it was refused
-
-# inspect a branch's pending diff without merging
-diff = table.branches.diff(exp)
-```
-
-Async: `await table.branches.merge(exp)`, `await table.branches.diff(exp)`.
-
-```typescript
-const branches = await table.branches();
-const exp = "experiment-reindex";
-
-// preview only (second arg is dryRun)
-const preview = await branches.merge(exp, true);
-
-// actually merge (default)
-const result = await branches.merge(exp);
-if (result.status === "merged") {
-  console.log("landed at", result.mainVersionAfter);
-} else if (result.status === "rejected") {
-  console.log(result.diff.mergeBlockers);
-}
-
-const diff = await branches.diff(exp);
-```
-
-The result is the wire JSON, containing `status` (`ready` on a passing dry run, `merged` on success, `rejected` when refused — also `notImplemented`/`unknown`), the branch `diff` (including `mergeBlockers` explaining any rejection), a `preview` of the columns that would be promoted, and — after a real merge — `mainVersionAfter`.
-
-### Merge preconditions
-
-Merge only **promotes newly added columns** onto main; it does not replay arbitrary commits. Practically, a branch is mergeable only if it has **exactly one commit since it was created, and that commit added a column**. The merge is rejected (`status: "rejected"`, with `mergeBlockers` set) if:
-
-- the branch was forked from another branch rather than directly from main
-- main has advanced since the branch was forked
-- the branch's rows changed since the fork (row counts must match main exactly)
-- the branch removed columns or changed a column's type/nullability
-- the branch added no columns (index-only changes are not merged)
-
-### Adding a column in a single commit
-
-Because the branch must contain just one column-adding commit, add the column with its values in one operation rather than add-then-backfill:
-
-1. **SQL transformation** — `add_columns` with a SQL expression computed from existing columns, so the column lands populated in one commit.
-2. **Precompute the values** — compute the column's values externally, then add the fully-populated column in a single operation (e.g. via `merge_insert`/`add_columns` with the data ready).
-3. **Lance-format-level data evolution (pylance)** — use Lance's data evolution with backfill, documented at <https://lance.org/guide/data_evolution/#with-data-backfill>.

-
-If you're connecting to a local table using OSS LanceDB, use this:
-```python
-db = lancedb.connect("./camelot-db") # local/OSS
-```
-If you're not sure which, or if you can't find the api_key or host_override params, ask the user.
 
 **Place the local database directory next to the script/entrypoint that opens it** (i.e. resolve the path relative to the script, `Path(__file__).parent / "camelot-db"`), not buried under a shared `data/` folder. The Lance dataset is the database, not a data file — keeping it beside its code makes ownership obvious and paths stable regardless of the working directory the script is launched from.

-## Python API reference
-
-`docs/src/python/python.md` is the entire Python API reference. It is maintained by
-hand, and anything not listed there is not rendered at all, so new public classes and
-module-level functions have to be added explicitly. How depends on the module:
-
-* `lancedb.index`, `lancedb.embeddings`, `lancedb.remote`, and `lancedb.rerankers` are
-  rendered by a single directive each, driven by the module's `__all__`. Add the new
-  name to `__all__` and it appears; forget, and it is silently omitted.
-* Everything else (`lancedb`, `lancedb.table`, `lancedb.query`, `lancedb.db`, ...) is
-  listed symbol by symbol. Add a `::: lancedb.<module>.<Name>` line to the matching
-  section, and remember that the page separates synchronous and asynchronous APIs.
-
-Deliberately undocumented: concrete implementations reached through an abstract base
-(`LanceTable`, `LanceDBConnection`, `RemoteDBConnection`), query base classes already
-covered by `inherited_members`, and internal helpers.
-
-Cross-references in docstrings use mkdocstrings syntax, `[text][lancedb.table.Table]`.
-Plain relative links such as `[Table](Table)` do not resolve. To check your work:
-
-```shell
-pip install -r docs/requirements.txt
-cd docs && PYTHONPATH=. mkdocs build
-```
-
-The docs site only builds on pushes to `main`, so this is not covered by PR CI.

-# Connecting to a LanceDB remote server
-
-LanceDB Enterprise/Cloud deployments are served by a server implementing the
-lance-namespace OpenAPI spec
-(<https://github.com/lance-format/lance-namespace/blob/main/docs/src/spec.yaml>).
-Every remote (`db://...`) connection talks to such a server, and some operations
-exist only there. In particular, all operations around jobs (listing, inspecting,
-creating, or canceling jobs) run server-side — there is no local/OSS equivalent, so
-resolve a server connection before attempting any job work. The job REST methods
-themselves are documented in `references/remote_jobs.md`.
-
-Every request needs two things:
-
-1. **Base URL** — the server endpoint
-2. **Credentials** — an API key (`x-api-key` header over REST), and usually a database name (`x-lancedb-database` header)
-
-## Resolution steps
-
-1. If the user already gave a URL and API key (or said which environment they're working against), use that.
-2. Otherwise, look for credentials already available in the environment:
-   - Env vars like `LANCEDB_URI` / `LANCEDB_HOST` / `LANCEDB_API_KEY`
-   - A server endpoint already running or port-forwarded locally (the REST default port is 2333, i.e. `http://localhost:2333`)
-3. If you didn't find both pieces, ask the user directly: **"What's your LanceDB endpoint's URL, and what's your API key?"** Also ask which database to use if it isn't obvious. Don't guess or probe further — the user knows their deployment.
-
-## Validating the connection
-
-Make a cheap authenticated request and check the status before starting real work:
-
-```bash
-curl -s -w "\n%{http_code}" "{base_url}/v1/table/?limit=1" \
-  -H "x-api-key: <key>" \
-  -H "x-lancedb-database: <database>"
-```
-
-- `200` — connection, key, and database header all good
-- `401` — API key missing or wrong
-- `400` mentioning a database header — this deployment expects `x-lancedb-database`
-
-## Non-REST equivalents
-
-The same credentials work through the SDKs and CLI:
-
-- Python SDK: `lancedb.connect("db://<database>", api_key="<key>", host_override="<base_url>")`
-- TypeScript SDK: `await lancedb.connect("db://<database>", { apiKey: "<key>", hostOverride: "<base_url>" })`
-- `lancedb` CLI: a `[profiles.<name>]` entry in `~/.lancedb/config.toml` with `http_server_url`, `api_key`, `database`

-# Job operations over the LanceDB remote server REST API
-
-Jobs are server-side background operations on LanceDB Enterprise/Cloud — index builds,
-column backfills, materialized view refreshes, and similar async work. Endpoints that
-trigger async work (e.g. the column backfill or materialized view refresh endpoints)
-return a `job_id`; these four methods are how you track and manage those jobs.
-
-Resolve the connection first — see `references/remote_connect.md`. All four methods
-are **POST** requests under `{base_url}/v1/jobs/` with JSON bodies, and take the usual
-`x-api-key` / `x-lancedb-database` headers. If every job call returns `501`, job APIs
-are disabled on that deployment (the server has no job registry configured) — report
-that rather than retrying.
-
-## 1. List jobs — `POST /v1/jobs/list`
-
-The body is optional; an empty body lists everything. All fields are filters:
-
-```json
-{
-  "limit": 100,
-  "table_name": "my_table",
-  "job_type": "...",
-  "job_subtype": "...",
-  "state": "...",
-  "page_token": "..."
-}
-```
-
-```bash
-curl -s -X POST "{base_url}/v1/jobs/list" \
-  -H "x-api-key: <key>" -H "x-lancedb-database: <database>" \
-  -H "content-type: application/json" \
-  -d '{"table_name": "my_table"}'
-```
-
-Response:
-
-```json
-{
-  "jobs": [
-    {
-      "job_id": "...",
-      "table": "my_table",
-      "job_type": "...",
-      "job_subtype": "...",
-      "state": "done",
-      "created_at_millis": 1720000000000
-    }
-  ],
-  "page_token": "..."
-}
-```
-
-A `page_token` in the response means there are more results — pass it back in the next
-request to continue. Note list rows use a lowercase `state` string, while describe uses
-an uppercase `job_state`.
-
-## 2. Describe a job — `POST /v1/jobs/describe`
-
-Body: `{"job_id": "<id>"}`. Returns full detail for one job:
-
-```json
-{
-  "job_id": "...",
-  "job_type": "...",
-  "job_subtype": "...",
-  "job_state": "IN_PROGRESS",
-  "creation_ms": 1720000000000,
-  "spec": {},
-  "status": {}
-}
-```
-
-`job_state` is one of `IN_PROGRESS`, `CANCELLED`, `FAILED`, `DONE`. `spec` and `status`
-are job-type-specific JSON objects (the job's input specification and its current
-progress/status). Returns `404` for an unknown job id.
-
-## 3. Cancel a job — `POST /v1/jobs/cancel`
-
-Body: `{"job_id": "<id>"}`; response echoes `{"job_id": "<id>"}`. Cancellation is a
-service-level operation requiring the same administrative authorization as the
-`/admin` routes — a database-scoped API key that can list and describe jobs may still
-get a permission error here. Other errors: `404` unknown job, `409` state conflict
-(e.g. already in a terminal state), `429` too much write contention (safe to retry).
-
-## 4. Query job event history — `POST /v1/jobs/query_events`
-
-Returns the event history (state transitions, progress updates) for one or more jobs.
-Body: `{"job_id": "<id>"}` for one job, or `{"job_ids": ["<id>", ...]}` for a batch.
-Optional fields: `limit` (max event rows), `limit_per_job` (per job in a batch query),
-and `filter` — a SQL-like expression over the columns `state`, `updated_by`,
-`owner_component`, and `claim_entity`. (`full_text_search` is reserved and currently
-rejected as not implemented.)
-
-The response is **not JSON** — it is an Arrow IPC stream
-(`content-type: application/vnd.apache.arrow.stream`). Decode it, e.g. in Python:
-
-```python
-import pyarrow.ipc
-import requests
-
-resp = requests.post(
-    f"{base_url}/v1/jobs/query_events",
-    headers={"x-api-key": key, "x-lancedb-database": database},
-    json={"job_id": job_id},
-)
-resp.raise_for_status()
-events = pyarrow.ipc.open_stream(resp.content).read_all()
-```
-
-## Feature engineering (Geneva) jobs
-
-Feature engineering jobs — UDF column backfills and materialized view refreshes run
-through Geneva — are tracked **separately** from the `/v1/jobs` registry above. Their
-records live in a `geneva_jobs` table inside the database itself (in the `__system`
-namespace), and you access them through a Python `geneva` connection rather than the
-REST endpoints above:
-
-```python
-import geneva
-from geneva.jobs import JobStateManager
-
-# Same credentials as lancedb.connect / the REST API
-conn = geneva.connect("db://<database>", api_key="<key>", host_override="<base_url>")
-jsm = JobStateManager(conn)
-
-# List jobs. NOTE: status defaults to "RUNNING"; pass status=None for all jobs.
-# Statuses: PENDING | RUNNING | DONE | FAILED | CANCELLED
-jobs = jsm.list_jobs(table_name="my_table", status=None)
-
-# Fetch one job by id (returns a list of JobRecord)
-records = jsm.get("<job_id>")
-```
-
-Each `JobRecord` has `table_name`, `column_name`, `job_id`, `job_type`, `status`,
-`launched_at`, `completed_at`, `config`, `launched_by`, `manifest_id`, `cluster_name`,
-`metrics` (progress counters), `events` (human-readable history), and `updated_at`.
-For filters `list_jobs` doesn't support (e.g. time ranges), query the underlying table
-directly: `jsm.get_table(True).search().where("launched_at >= TIMESTAMP '...'")` —
-pass `True` to check out the latest version, since other processes update job state.
-
-Stale-status caveat: nothing reaps dead Geneva jobs, so a job can sit in
-`RUNNING`/`PENDING` forever if its worker died. Treat a job as effectively `FAILED`
-when it has been running longer than ~36 hours, or its `updated_at` is more than ~2
-hours old (this matches the heuristic the Geneva console UI applies on read).
-
-## Workflow tips
-
-- To wait for async work (a backfill, an index build), poll `describe` until
-  `job_state` leaves `IN_PROGRESS`; on `FAILED`, pull `status` and `query_events` for
-  the failure detail.

-### Pre-Haswell x86_64 hosts: `lancedb-compat`
-
-The default `lancedb` wheel targets `x86-64-haswell` (AVX2 + FMA + F16C) for full performance on modern hardware. Pre-Haswell hosts — Intel Sandy Bridge / Ivy Bridge / Westmere; AMD Bulldozer / Piledriver / Steamroller — don't have AVX2 and crash with `Illegal instruction` at `import lancedb`.
-
-For those hosts, install the `lancedb-compat` package instead:
-
-```bash
-pip install lancedb-compat
-```
-
-Same Python API (`import lancedb` works as usual). The compat wheel is compiled at the `x86-64-v2` baseline (Nehalem-class) and uses runtime SIMD dispatch in the embedded lance crate to pick the right kernel tier (scalar / AVX / AVX+FMA / AVX2+FMA / AVX-512) at load time, so it still goes fast on modern hardware while running cleanly on the pre-Haswell silicon. Use `lance.simd_info()` from Python to verify which tier was selected.
-
-`lancedb` and `lancedb-compat` install to the same `lancedb/` namespace and conflict at install time. Pick one. To switch, `pip uninstall lancedb` first, then `pip install lancedb-compat` (or vice-versa).
-
-If you need a custom baseline (or `lancedb-compat` isn't yet published for your platform), build from source with the override:
-
-```bash
-RUSTFLAGS="-C target-cpu=x86-64-v2" maturin build --release
-pip install ./target/wheels/lancedb-*.whl
-```
-
 ### Preview Releases
 
 Stable releases are created about every 2 weeks. For the latest features and bug fixes, you can install the preview release. These releases receive the same level of testing as stable releases, but are not guaranteed to be available for more than 6 months after they are released. Once your application is stable, we recommend switching to stable releases.
