Bump version: 0.21.1-beta.0 → 0.21.1

We attempted to make pylance optional in
https://github.com/lancedb/lancedb/pull/2156 but it appears this did not

reverts the optional-ness so we can get back in a working state while we
fix the issue.

+# Contributing to LanceDB
+
+LanceDB is an open-source project and we welcome contributions from the community.
+This document outlines the process for contributing to LanceDB.
+
+## Reporting Issues
+
+If you encounter a bug or have a feature request, please open an issue on the
+[GitHub issue tracker](https://github.com/lancedb/lancedb).
+
+## Picking an issue
+
+We track issues on the GitHub issue tracker. If you are looking for something to
+work on, check the [good first issue](https://github.com/lancedb/lancedb/contribute) label. These issues are typically the best described and have the smallest scope.
+
+If there's an issue you are interested in working on, please leave a comment on the issue. This will help us avoid duplicate work. Additionally, if you have questions about the issue, please ask them in the issue comments. We are happy to provide guidance on how to approach the issue.
+
+## Configuring Git
+
+First, fork the repository on GitHub, then clone your fork:
+
+```bash
+git clone https://github.com/<username>/lancedb.git
+cd lancedb
+```
+
+Then add the main repository as a remote:
+
+```bash
+git remote add upstream https://github.com/lancedb/lancedb.git
+git fetch upstream
+```
+
+## Setting up your development environment
+
+We have development environments for Python, Typescript, and Java. Each environment has its own setup instructions.
+
+* [Python](python/CONTRIBUTING.md)
+* [Typescript](nodejs/CONTRIBUTING.md)
+<!-- TODO: add Java contributing guide -->
+* [Documentation](docs/README.md)
+
+
+## Best practices for pull requests
+
+For the best chance of having your pull request accepted, please follow these guidelines:
+
+1. Unit test all bug fixes and new features. Your code will not be merged if it
+   doesn't have tests.
+1. If you change the public API, update the documentation in the `docs` directory.
+1. Aim to minimize the number of changes in each pull request. Keep to solving
+   one problem at a time, when possible.
+1. Before marking a pull request ready-for-review, do a self review of your code.
+   Is it clear why you are making the changes? Are the changes easy to understand?
+1. Use [conventional commit messages](https://www.conventionalcommits.org/en/) as pull request titles. Examples:
+    * New feature: `feat: adding foo API`
+    * Bug fix: `fix: issue with foo API`
+    * Documentation change: `docs: adding foo API documentation`
+1. If your pull request is a work in progress, leave the pull request as a draft.
+   We will assume the pull request is ready for review when it is opened.
+1. When writing tests, test the error cases. Make sure they have understandable
+   error messages.
+
+## Project structure
+
+The core library is written in Rust. The Python, Typescript, and Java libraries
+are wrappers around the Rust library.
+
+* `src/lancedb`: Rust library source code
+* `python`: Python package source code
+* `nodejs`: Typescript package source code
+* `node`: **Deprecated** Typescript package source code
+* `java`: Java package source code
+* `docs`: Documentation source code
+
+## Release process
+
+For information on the release process, see: [release_process.md](release_process.md)

 ## Building the docs
 
 ### Setup
-1. Install LanceDB. From LanceDB repo root: `pip install -e python`
+1. Install LanceDB Python. See setup in [Python contributing guide](../python/CONTRIBUTING.md).
-2. Install dependencies. From LanceDB repo root: `pip install -r docs/requirements.txt`
+   Run `make develop` to install the Python package.
-3. Make sure you have node and npm setup
+2. Install documentation dependencies. From LanceDB repo root: `pip install -r docs/requirements.txt`
-4. Make sure protobuf and libssl are installed
 
-### Building node module and create markdown files
+### Preview the docs
 
-See [Javascript docs README](./src/javascript/README.md)
+```shell
-
-### Build docs
-From LanceDB repo root:
-
-Run: `PYTHONPATH=. mkdocs build -f docs/mkdocs.yml`
-
-If successful, you should see a `docs/site` directory that you can verify locally.
-
-### Run local server
-
-You can run a local server to test the docs prior to deployment by navigating to the `docs` directory and running the following command:
-
-```bash
 cd docs
 mkdocs serve
 ```
 
-### Run doctest for typescript example
+If you want to just generate the HTML files:
 
-```bash
+```shell
-cd lancedb/docs
+PYTHONPATH=. mkdocs build -f docs/mkdocs.yml
-npm i
+```
-npm run build
+
-npm run all
+If successful, you should see a `docs/site` directory that you can verify locally.
+
+## Adding examples
+
+To make sure examples are correct, we put examples in test files so they can be
+run as part of our test suites.
+
+You can see the tests are at:
+
+* Python: `python/python/tests/docs`
+* Typescript: `nodejs/examples/`
+
+### Checking python examples
+
+```shell
+cd python
+pytest -vv python/tests/docs
+```
+
+### Checking typescript examples
+
+The `@lancedb/lancedb` package must be built before running the tests:
+
+```shell
+pushd nodejs
+npm ci
+npm run build
+popd
+```
+
+Then you can run the examples by going to the `nodejs/examples` directory and
+running the tests like a normal npm package:
+
+```shell
+pushd nodejs/examples
+npm ci
+npm test
+popd
+```
+
+## API documentation
+
+### Python
+
+The Python API documentation is organized based on the file `docs/src/python/python.md`.
+We manually add entries there so we can control the organization of the reference page.
+**However, this means any new types must be manually added to the file.** No additional
+steps are needed to generate the API documentation.
+
+### Typescript
+
+The typescript API documentation is generated from the typescript source code using [typedoc](https://typedoc.org/).
+
+When new APIs are added, you must manually re-run the typedoc command to update the API documentation.
+The new files should be checked into the repository.
+
+```shell
+pushd nodejs
+npm run docs
+popd
 ```

 Now you can use this embedding function to create your table schema and that's it! you can then ingest data and run queries without manually vectorizing the inputs.

+# Variable and Secrets
+
+Most embedding configuration options are saved in the table's metadata. However,
+this isn't always appropriate. For example, API keys should never be stored in the
+metadata. Additionally, other configuration options might be best set at runtime,
+such as the `device` configuration that controls whether to use GPU or CPU for
+inference. If you hardcoded this to GPU, you wouldn't be able to run the code on
+a server without one.
+
+To handle these cases, you can set variables on the embedding registry and
+reference them in the embedding configuration. These variables will be available
+during the runtime of your program, but not saved in the table's metadata. When
+the table is loaded from a different process, the variables must be set again.
+
+To set a variable, use the `set_var()` / `setVar()` method on the embedding registry.
+To reference a variable, use the syntax `$env:VARIABLE_NAME`. If there is a default
+value, you can use the syntax `$env:VARIABLE_NAME:DEFAULT_VALUE`.
+
+## Using variables to set secrets
+
+Sensitive configuration, such as API keys, must either be set as environment
+variables or using variables on the embedding registry. If you pass in a hardcoded
+value, LanceDB will raise an error. Instead, if you want to set an API key via
+configuration, use a variable:

+## Using variables to set the device parameter
+
+Many embedding functions that run locally have a `device` parameter that controls
+whether to use GPU or CPU for inference. Because not all computers have a GPU,
+it's helpful to be able to set the `device` parameter at runtime, rather than
+have it hard coded in the embedding configuration. To make it work even if the
+variable isn't set, you could provide a default value of `cpu` in the embedding
+configuration.
+
+Some embedding libraries even have a method to detect which devices are available,
+which could be used to dynamically set the device at runtime. For example, in Python
+you can check if a CUDA GPU is available using `torch.cuda.is_available()`.

     ### Add a PyArrow table
 
     If you have data coming in as a PyArrow table, you can add it directly to the LanceDB table.
 
-    ```python

-    pa_table = pa.Table.from_arrays(
-            [
-                pa.array([[9.1, 6.7], [9.9, 31.2]],

         ```
 
     ### Add a Pydantic Model
 
     Assuming that a table has been created with the correct schema as shown [above](#creating-empty-table), you can add data items that are valid Pydantic models to the table.
 
-    ```python
+    === "Sync API"
-    pydantic_model_items = [
-        Item(vector=[8.1, 4.7], item="pineapple", price=10.0),
-        Item(vector=[6.9, 9.3], item="avocado", price=9.0)

     ??? "Ingesting Pydantic models with LanceDB embedding API"
         When using LanceDB's embedding API, you can add Pydantic models directly to the table. LanceDB will automatically convert the `vector` field to a vector before adding it to the table. You need to specify the default value of `vector` field as None to allow LanceDB to automatically vectorize the data.

@@ -0,0 +1,135 @@
+The merge insert command is a flexible API that can be used to perform:
+
+1. Upsert
+2. Insert-if-not-exists
+3. Replace range
+
+It works by joining the input data with the target table on a key you provide.
+Often this key is a unique row id key. You can then specify what to do when
+there is a match and when there is not a match. For example, for upsert you want
+to update if the row has a match and insert if the row doesn't have a match.
+Whereas for insert-if-not-exists you only want to insert if the row doesn't have
+a match.
+
+You can also read more in the API reference:

+* Typescript: [lancedb.Table.mergeInsert](../../js/classes/Table.md/#mergeinsert)
+
+!!! tip "Use scalar indices to speed up merge insert"
+
+    The merge insert command needs to perform a join between the input data and the
+    target table on the `on` key you provide. This requires scanning that entire
+    column, which can be expensive for large tables. To speed up this operation,
+    you can create a scalar index on the `on` column, which will allow LanceDB to
+    find matches without having to scan the whole tables.
+
+    Read more about scalar indices in [Building a Scalar Index](../scalar_index.md)
+    guide.
+
+!!! info "Embedding Functions"
+
+    Like the create table and add APIs, the merge insert API will automatically
+    compute embeddings if the table has a embedding definition in its schema.
+    If the input data doesn't contain the source column, or the vector column
+    is already filled, then the embeddings won't be computed. See the
+    [Embedding Functions](../../embeddings/embedding_functions.md) guide for more
+    information.
+
+## Upsert
+
+Upsert updates rows if they exist and inserts them if they don't. To do this
+with merge insert, enable both `when_matched_update_all()` and
+`when_not_matched_insert_all()`.

+
+!!! note "Providing subsets of columns"
+
+    If a column is nullable, it can be omitted from input data and it will be
+    considered `null`. Columns can also be provided in any order.
+
+## Insert-if-not-exists
+
+To avoid inserting duplicate rows, you can use the insert-if-not-exists command.
+This will only insert rows that do not have a match in the target table. To do
+this with merge insert, enable just `when_not_matched_insert_all()`.

+
+
+## Replace range
+
+You can also replace a range of rows in the target table with the input data.
+For example, if you have a table of document chunks, where each chunk has
+both a `doc_id` and a `chunk_id`, you can replace all chunks for a given
+`doc_id` with updated chunks. This can be tricky otherwise because if you
+try to use upsert when the new data has fewer chunks you will end up with
+extra chunks. To avoid this, add another clause to delete any chunks for
+the document that are not in the new data, with
+`when_not_matched_by_source_delete`.

 Hybrid Search is a broad (often misused) term. It can mean anything from combining multiple methods for searching, to applying ranking methods to better sort the results. In this blog, we use the definition of "hybrid search" to mean using a combination of keyword-based and vector search.

-
-LanceDb uses [biome](https://biomejs.dev/) for linting and formatting. if you are using VSCode you will need to install the official [Biome](https://marketplace.visualstudio.com/items?itemName=biomejs.biome) extension.
-To manually lint your code you can run:
-
-```sh
-npm run lint
-```
-
-to automatically fix all fixable issues:
-
-```sh

+
+The distance metric used to train the index.
+
+Default value is "l2".
+
+The following distance types are available:
+
+"l2" - Euclidean distance. This is a very common distance metric that
+accounts for both magnitude and direction when determining the distance
+between vectors. L2 distance has a range of [0, ∞).
+
+"cosine" - Cosine distance.  Cosine distance is a distance metric
+calculated from the cosine similarity between two vectors. Cosine
+similarity is a measure of similarity between two non-zero vectors of an
+inner product space. It is defined to equal the cosine of the angle
+between them.  Unlike L2, the cosine distance is not affected by the
+magnitude of the vectors.  Cosine distance has a range of [0, 2].
+
+"dot" - Dot product. Dot distance is the dot product of two vectors. Dot
+distance has a range of (-∞, ∞). If the vectors are normalized (i.e. their
+L2 norm is 1), then dot distance is equivalent to the cosine distance.

+
+### efConstruction?

+```ts
+optional efConstruction: number;
+```
+
+The number of candidates to evaluate during the construction of the HNSW graph.
+
+The default value is 300.
+
+This value controls the tradeoff between build speed and accuracy.
+The higher the value the more accurate the build but the slower it will be.
+150 to 300 is the typical range. 100 is a minimum for good quality search
+results. In most cases, there is no benefit to setting this higher than 500.
+This value should be set to a value that is not less than `ef` in the search phase.
+
+***
+
+### m?
+
+```ts
+optional m: number;
+```
+
+The number of neighbors to select for each vector in the HNSW graph.
+
+The default value is 20.
+
+This value controls the tradeoff between search speed and accuracy.
+The higher the value the more accurate the search but the slower it will be.
+
+***
+
+### maxIterations?
+
+```ts
+optional maxIterations: number;
+```
+
+Max iterations to train kmeans.
+
+The default value is 50.
+
+When training an IVF index we use kmeans to calculate the partitions.  This parameter
+controls how many iterations of kmeans to run.
+
+Increasing this might improve the quality of the index but in most cases the parameter
+is unused because kmeans will converge with fewer iterations.  The parameter is only
+used in cases where kmeans does not appear to converge.  In those cases it is unlikely
+that setting this larger will lead to the index converging anyways.
+
+***
+
+### numPartitions?
+
+```ts
+optional numPartitions: number;
+```
+
+The number of IVF partitions to create.
+
+For HNSW, we recommend a small number of partitions. Setting this to 1 works
+well for most tables. For very large tables, training just one HNSW graph
+will require too much memory. Each partition becomes its own HNSW graph, so
+setting this value higher reduces the peak memory use of training.
+
+***
+
+### numSubVectors?
+
+```ts
+optional numSubVectors: number;
+```
+
+Number of sub-vectors of PQ.
+
+This value controls how much the vector is compressed during the quantization step.
+The more sub vectors there are the less the vector is compressed.  The default is
+the dimension of the vector divided by 16.  If the dimension is not evenly divisible
+by 16 we use the dimension divded by 8.
+
+The above two cases are highly preferred.  Having 8 or 16 values per subvector allows
+us to use efficient SIMD instructions.
+
+If the dimension is not visible by 8 then we use 1 subvector.  This is not ideal and
+will likely result in poor performance.
+
+***
+
+### sampleRate?
+
+```ts
+optional sampleRate: number;
+```
+
+The rate used to calculate the number of training vectors for kmeans.
+
+Default value is 256.
+
+When an IVF index is trained, we need to calculate partitions.  These are groups
+of vectors that are similar to each other.  To do this we use an algorithm called kmeans.
+
+Running kmeans on a large dataset can be slow.  To speed this up we run kmeans on a
+random sample of the data.  This parameter controls the size of the sample.  The total
+number of vectors used to train the index is `sample_rate * num_partitions`.
+
+Increasing this value might improve the quality of the index but in most cases the
+default should be sufficient.

 LanceDB supports [Polars](https://github.com/pola-rs/polars), a blazingly fast DataFrame library for Python written in Rust. Just like in Pandas, the Polars integration is enabled by PyArrow under the hood.
