0579303602 feat: allow setting custom Session on ListingDatabase (#2526)
## Summary

Add support for providing a custom `Session` when connecting to a
`ListingDatabase`. This allows users to configure object store
registries, caching, and other session-related settings while
maintaining full backward compatibility.

## Usage Example

```rust
use std::sync::Arc;
use lancedb::connect;

let custom_session = Arc::new(lance::session::Session::default());

let db = connect("/path/to/database")
    .session(custom_session)
    .execute()
    .await?;
```

88283110f4 fix: handle input with missing columns when using embedding functions (#2516)
## Summary

Fixes #2515 by implementing comprehensive support for missing columns in
Arrow table inputs when using embedding functions.

### Problem
Previously, when an Arrow table was passed to `fromDataToBuffer` with
missing columns and a schema containing embedding functions, the system
would fail because `applyEmbeddingsFromMetadata` expected all columns to
be present in the table.

ab8cbe62dd fix: excessive object storage handle creation in create_table (#2505)
This fixes two bugs with create_table storage handle reuse. First issue
is, the database object did not previously carry a session that
create_table operations could reuse for create_table operations.

Second issue is, the inheritance logic for create_table and open_table
was causing empty storage options (i.e Some({})) to get sent, instead of
None. Lance handles these differently:

* When None is set, the object store held in the session's storage
registry that was created at "connect" is used. This value stays in the
cache long-term (probably as long as the db reference is held).
* When Some({}) is sent, LanceDB will create a new connection and cache
it for an empty key. However, that cached value will remain valid only
as long as the client holds a reference to the table. After that, the
cache is poisoned and the next create_table with the same key, will
create a new connection. This confounds reuse if e.g python gc's the
table object before another table is created.

My feeling is that the second path, if intentional, is probably meant to
serve cases where tables are overriding settings and the cached
connection is assumed not to be generally applicable. The bug is we were
engaging that mechanism for all tables.

f076bb41f4 feat: add support for returning all scores with rerankers (#2509)
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

4c999fb651 chore: fix cleanupOlderThan docs (#2504)
Thanks for all your work.

The docstring for `OptimizeOptions ` seems to reference a non-existent
method on `Table`. I believe this is the correct example for
`cleanupOlderThan`.

This also appears in the generated docs, but I assume they live
downstream from this code?

eb9784d7f2 feat(python): batch Ollama embed calls (#2453)
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.

4beb2d2877 fix(python): make sure explain_plan works with FTS queries (#2466)
## 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

Closes #2465

## Summary by CodeRabbit

* **Tests**
* Added new test cases to verify explain plan output for full-text
search, vector queries with pagination, and queries with filters.

* **Bug Fixes**
* Improved the accuracy of explain plan and analysis output for
full-text search queries, ensuring the correct query details are
reflected.

* **Refactor**
* Enhanced the formatting and hierarchical structure of execution plans
for hybrid queries, providing clearer and more detailed plan
representations.

5c7f63388d feat!: upgrade lance to v0.28.0 (#2404)
this introduces some breaking changes in terms of rust API of creating
FTS index, and the default index params changed

Signed-off-by: BubbleCal <bubble-cal@outlook.com>

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

- **New Features**
- Updated default settings for full-text search (FTS) index creation:
stemming, stop word removal, and ASCII folding are now enabled by
default, while token position storage is disabled by default.

- **Refactor**
- Simplified and streamlined the configuration and handling of FTS index
parameters for improved maintainability and consistency across
interfaces.
- Enhanced serialization and request construction for FTS index
parameters to reduce manual handling and improve code clarity.
- Improved test coverage by explicitly enabling positional indexing in
FTS tests to support phrase queries.

- **Chores**
- Upgraded all internal dependencies related to FTS indexing to the
latest version for enhanced compatibility and performance.
- Updated package versions for Node.js, Python, and Rust components to
the latest beta releases.
- Improved CI workflows by adding Rust toolchain setup with formatting
and linting tools.

# SQL Querying
You can use DuckDB and Apache Datafusion to query your LanceDB tables using SQL.
This guide will show how to query Lance tables them using both.
We will re-use the dataset [created previously](./tables.md):
```python
import lancedb
db = lancedb.connect("data/sample-lancedb")
data = [
{"vector": [3.1, 4.1], "item": "foo", "price": 10.0},
{"vector": [5.9, 26.5], "item": "bar", "price": 20.0}
]
table = db.create_table("pd_table", data=data)
```
## Querying a LanceDB Table with DuckDb
The `to_lance` method converts the LanceDB table to a `LanceDataset`, which is accessible to DuckDB through the Arrow compatibility layer.
To query the resulting Lance dataset in DuckDB, all you need to do is reference the dataset by the same name in your SQL query.
```python
import duckdb
arrow_table = table.to_lance()
duckdb.query("SELECT * FROM arrow_table")
```
| vector | item | price |
| ----------- | ---- | ----- |
| [3.1, 4.1] | foo | 10.0 |
| [5.9, 26.5] | bar | 20.0 |
## Querying a LanceDB Table with Apache Datafusion
Have the required imports before doing any querying.

### maximumNprobes()
```ts
maximumNprobes(maximumNprobes): VectorQuery
```
Set the maximum number of probes used.
This controls the maximum number of partitions that will be searched. If this
number is greater than minimumNprobes then the excess partitions will _only_ be
searched if we have not found enough results. This can be useful when there is
a narrow filter to allow these queries to spend more time searching and avoid
potential false negatives.
#### Parameters
* **maximumNprobes**: `number`
#### Returns

### minimumNprobes()
```ts
minimumNprobes(minimumNprobes): VectorQuery
```
Set the minimum number of probes used.
This controls the minimum number of partitions that will be searched. This
parameter will impact every query against a vector index, regardless of the
filter. See `nprobes` for more details. Higher values will increase recall
but will also increase latency.

your actual data to find the smallest possible value that will still give
you the desired recall.
For more fine grained control over behavior when you have a very narrow filter
you can use `minimumNprobes` and `maximumNprobes`. This method sets both
the minimum and maximum to the same value.

# Apache Datafusion
In Python, LanceDB tables can also be queried with [Apache Datafusion](https://datafusion.apache.org/), an extensible query engine written in Rust that uses Apache Arrow as its in-memory format. This means you can write complex SQL queries to analyze your data in LanceDB.
This integration is done via [Datafusion FFI](https://docs.rs/datafusion-ffi/latest/datafusion_ffi/), which provides a native integration between LanceDB and Datafusion.
The Datafusion FFI allows to pass down column selections and basic filters to LanceDB, reducing the amount of scanned data when executing your query. Additionally, the integration allows streaming data from LanceDB tables which allows to do aggregation larger-than-memory.
We can demonstrate this by first installing `datafusion` and `lancedb`.
```shell
pip install datafusion lancedb
```
We will re-use the dataset [created previously](./pandas_and_pyarrow.md):
```python
import lancedb
from datafusion import SessionContext
from lance import FFILanceTableProvider
db = lancedb.connect("data/sample-lancedb")
data = [
{"vector": [3.1, 4.1], "item": "foo", "price": 10.0},
{"vector": [5.9, 26.5], "item": "bar", "price": 20.0}
]
lance_table = db.create_table("lance_table", data)
ctx = SessionContext()
ffi_lance_table = FFILanceTableProvider(
lance_table.to_lance(), with_row_id=True, with_row_addr=True
)
ctx.register_table_provider("ffi_lance_table", ffi_lance_table)
```
The `to_lance` method converts the LanceDB table to a `LanceDataset`, which is accessible to Datafusion through the Datafusion FFI integration layer.
To query the resulting Lance dataset in Datafusion, you first need to register the dataset with Datafusion and then just reference it by the same name in your SQL query.
```python
ctx.table("ffi_lance_table")
ctx.sql("SELECT * FROM ffi_lance_table")
```
```
┌─────────────┬─────────┬────────┬─────────────────┬─────────────────┐

# LanceDB Java SDK
## Configuration and Initialization
### LanceDB Cloud
For LanceDB Cloud, use the simplified builder API:
```java
import com.lancedb.lance.namespace.LanceRestNamespace;
// If your DB url is db://example-db, then your database here is example-db
LanceRestNamespace namespace = LanceDBRestNamespaces.builder()
.apiKey("your_lancedb_cloud_api_key")
.database("your_database_name")
.build();
```
### LanceDB Enterprise
For Enterprise deployments, use your VPC endpoint:
```java
LanceRestNamespace namespace = LanceDBRestNamespaces.builder()
.apiKey("your_lancedb_enterprise_api_key")
.database("your-top-dir") // Your top level folder under your cloud bucket, e.g. s3://your-bucket/your-top-dir/
.hostOverride("http://<vpc_endpoint_dns_name>:80")
.build();
```
## Development
Build:
```shell
./mvnw install
```
