## Summary
Fixed a minor grammar error in the error message for missing API key
when connecting to LanceDB cloud.
## Changes
- Changed 'api_key is required to connected LanceDB cloud' to 'api_key
is required to connect to LanceDB cloud'
- Location: `python/python/lancedb/__init__.py:95`
## Test plan
- Error message formatting is correct and grammatical
- No functional changes to existing behavior
## Summary
- Add `create_import_stub()` helper to `embeddings/utils.py` for
handling optional dependencies
- Fix MLX doctest collection failures by using import stubs in
`gte_mlx_model.py`
- Module now imports successfully for doctest collection even when MLX
is not installed
## Changes
- **New utility function**: `create_import_stub()` creates placeholder
objects that allow class inheritance but raise helpful errors when used
- **Updated MLX model**: Uses import stubs instead of direct imports
that fail immediately
- **Graceful degradation**: Clear error messages when MLX functionality
is accessed without MLX installed
## Test Results
- ✅ `pytest --doctest-modules python/lancedb` now passes (with and
without MLX installed)
- ✅ All existing tests continue to pass
- ✅ MLX functionality works normally when MLX is installed
- ✅ Helpful error messages when MLX functionality is used without MLX
installed
Fixes#2538

this test adds a new vector and then performs vector search with
distance range.
this may fail if the new vector becomes the closest one to the query
vector

Previously `return_score="all"` was supported only for the default
reranker (RRF) and not the model based rerankers.
This adds support for keeping all scores in the base reranker so that
all model based rerankers can use it. Its a slower path than keeping
just the relevance score but can be useful in debugging
just noticed that we're doing a 'return' instead of a 'raise' while
trying to get remote functionality working for my project. I went ahead
and implemented tests for both of the unimplemented functions (to_pandas
and to_arrow) while I was in there.

Other embedding integrations such as Cohere and OpenAI already send
requests in batches. We should do that for Ollama too to improve
throughput.
The Ollama [`.embed`
API](63ca747622/ollama/_client.py (L359-L378))
was added in version 0.3.0 (almost a year ago) so I updated the version
requirement in pyproject.
<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit
- **Bug Fixes**
- Improved compatibility with newer versions of the "ollama" package by
requiring version 0.3.0 or higher.
- Enhanced embedding generation to process batches of texts more
efficiently and reliably.
- **Refactor**
- Improved type consistency and clarity for embedding-related methods.

## Summary
Fixes issue #2465 where FTS explain plans only showed basic `LanceScan`
instead of detailed execution plans with FTS query details, limits, and
offsets.
## Root Cause
The `FTSQuery::explain_plan()` and `analyze_plan()` methods were missing
the `.full_text_search()` call before calling explain/analyze plan,
causing them to operate on the base query without FTS context.
## Changes
- **Fixed** `explain_plan()` and `analyze_plan()` in `src/query.rs` to
call `.full_text_search()`
- **Added comprehensive test coverage** for FTS explain plans with
limits, offsets, and filters
- **Updated existing tests** to expect correct behavior instead of buggy
behavior
## Before/After
**Before (broken):**
```
LanceScan: uri=..., projection=[...], row_id=false, row_addr=false, ordered=true
```
**After (fixed):**
```
ProjectionExec: expr=[id@2 as id, text@3 as text, _score@1 as _score]
Take: columns="_rowid, _score, (id), (text)"
CoalesceBatchesExec: target_batch_size=1024
GlobalLimitExec: skip=2, fetch=4
MatchQuery: query=test
```
## Test Plan
- [x] All new FTS explain plan tests pass
- [x] Existing tests continue to pass
- [x] FTS queries now show proper execution plans with MatchQuery,
limits, filters

Provides the ability to set a timeout for merge insert. The default
underlying timeout is however long the first attempt takes, or if there
are multiple attempts, 30 seconds. This has two use cases:
1. Make the timeout shorter, when you want to fail if it takes too long.
2. Allow taking more time to do retries.

## Summary by CodeRabbit
- **New Features**
- Added support for specifying a timeout when performing merge insert
operations in Python, Node.js, and Rust APIs.
- Introduced a new option to control the maximum allowed execution time
for merge inserts, including retry timeout handling.
- **Documentation**
- Updated and added documentation to describe the new timeout option and

Based on this comment:
https://github.com/lancedb/lancedb/issues/2228#issuecomment-2730463075
and https://github.com/lancedb/lance/pull/2357
Here is my attempt at implementing bindings for returning merge stats
from a `merge_insert.execute` call for lancedb.
Note: I have almost no idea what I am doing in Rust but tried to follow
existing code patterns and pay attention to compiler hints.
- The change in nodejs binding appeared to be necessary to get
compilation to work, presumably this could actual work properly by
returning some kind of NAPI JS object of the stats data?
- I am unsure of what to do with the remote/table.rs changes -
necessarily for compilation to work; I assume this is related to LanceDB
cloud, but unsure the best way to handle that at this point.
Proof of function:
```python
import pandas as pd
import lancedb
db = lancedb.connect("/tmp/test.db")
test_data = pd.DataFrame(
{
"title": ["Hello", "Test Document", "Example", "Data Sample", "Last One"],
"id": [1, 2, 3, 4, 5],
"content": [
"World",
"This is a test",
"Another example",
"More test data",
"Final entry",
],
}
)
table = db.create_table("documents", data=test_data, exist_ok=True, mode="overwrite")
update_data = pd.DataFrame(
{
"title": [
"Hello, World",
"Test Document, it's good",
"Example",
"Data Sample",
"Last One",
"New One",
],
"id": [1, 2, 3, 4, 5, 6],
"content": [
"World",
"This is a test",
"Another example",
"More test data",
"Final entry",
"New content",
],
}
)
stats = (
table.merge_insert(on="id")
.when_matched_update_all()
.when_not_matched_insert_all()
.execute(update_data)
)
print(stats)
```
returns
```
{'num_inserted_rows': 1, 'num_updated_rows': 5, 'num_deleted_rows': 0}
```
