+LanceDB does not automatically create the ANN index for two reasons. The first is that it's optimized

 While PQ helps with reducing the size of the index, IVF primarily addresses search performance. The primary purpose of an inverted file index is to facilitate rapid and effective nearest neighbor search by narrowing down the search space.
 
-In IVF, the PQ vector space is divided into *Voronoi cells*, which are essentially partitions that consist of all the points in the space that are within a threshold distance of the given region's seed point. These seed points are used to create an inverted index that correlates each centroid with a list of vectors in the space, allowing a search to be restricted to just a subset of vectors in the index.

-## FAQ
-
-### When is it necessary to create a vector index?
-
-LanceDB has manually-tuned SIMD code for computing vector distances. In our benchmarks, computing 100K pairs of 1K dimension vectors takes **<20ms**. For small datasets (<100K rows) or applications that can accept up to 100ms latency, vector indices are usually not necessary.
-
-For large-scale or higher dimension vectors, it is beneficial to create vector index.
-
-### How big is my index, and how much memory will it take?
-
-In LanceDB, all vector indices are disk-based, meaning that when responding to a vector query, only the relevant pages from the index file are loaded from disk and cached in memory. Additionally, each sub-vector is usually encoded into 1 byte PQ code.
-
-For example, with 1024-dimension vectors, if we choose `num_sub_vectors = 64`, each sub-vector has `1024 / 64 = 16` float32 numbers. Product quantization can lead to approximately `16 * sizeof(float32) / 1 = 64` times of space reduction.
-
-### How to choose `num_partitions` and `num_sub_vectors` for IVF_PQ index?
-
-`num_partitions` is used to decide how many partitions the first level IVF index uses. Higher number of partitions could lead to more efficient I/O during queries and better accuracy, but it takes much more time to train. On SIFT-1M dataset, our benchmark shows that keeping each partition 1K-4K rows lead to a good latency/recall.
-
-`num_sub_vectors` specifies how many PQ short codes to generate on each vector. Because PQ is a lossy compression of the original vector, a higher `num_sub_vectors` usually results in less space distortion, and thus yields better accuracy. However, a higher `num_sub_vectors` also causes heavier I/O and more PQ computation, and thus, higher latency. `dimension / num_sub_vectors` should be a multiple of 8 for optimum SIMD efficiency.

+### Imagebind embeddings
+We have support for [imagebind](https://github.com/facebookresearch/ImageBind) model embeddings. You can download our version of the packaged model via - `pip install imagebind-packaged==0.1.2`.
+
+This function is registered as `imagebind` and supports Audio, Video and Text modalities(extending to Thermal,Depth,IMU data):
+
+| Parameter | Type | Default Value | Description |
+|---|---|---|---|
+| `name` | `str` | `"imagebind_huge"` | Name of the model. |
+| `device` | `str` | `"cpu"` | The device to run the model on. Can be `"cpu"` or `"gpu"`. |
+| `normalize` | `bool` | `False` | set to `True` to normalize your inputs before model ingestion. |
+
+Below is an example demonstrating how the API works:
+
+```python
+db = lancedb.connect(tmp_path)
+registry = EmbeddingFunctionRegistry.get_instance()
+func = registry.get("imagebind").create()
+
+class ImageBindModel(LanceModel):
+    text: str
+    image_uri: str = func.SourceField()
+    audio_path: str
+    vector: Vector(func.ndims()) = func.VectorField()
+
+# add locally accessible image paths
+text_list=["A dog.", "A car", "A bird"]
+image_paths=[".assets/dog_image.jpg", ".assets/car_image.jpg", ".assets/bird_image.jpg"]
+audio_paths=[".assets/dog_audio.wav", ".assets/car_audio.wav", ".assets/bird_audio.wav"]
+
+# Load data
+inputs = [
+    {"text": a, "audio_path": b, "image_uri": c}
+    for a, b, c in zip(text_list, audio_paths, image_paths)
+]
+
+#create table and add data
+table = db.create_table("img_bind", schema=ImageBindModel)
+table.add(inputs)
+```
+
+Now, we can search using any modality:
+
+#### image search
+```python
+query_image = "./assets/dog_image2.jpg" #download an image and enter that path here
+actual = table.search(query_image).limit(1).to_pydantic(ImageBindModel)[0]
+print(actual.text == "dog")
+```
+#### audio search
+
+```python
+query_audio = "./assets/car_audio2.wav" #download an audio clip and enter path here
+actual = table.search(query_audio).limit(1).to_pydantic(ImageBindModel)[0]
+print(actual.text == "car")
+```
+#### Text search
+You can add any input query and fetch the result as follows:
+```python
+query = "an animal which flies and tweets" 
+actual = table.search(query).limit(1).to_pydantic(ImageBindModel)[0]
+print(actual.text == "bird")
+```
+

-## Applying an embedding function to data
-
-=== "Python"
-    Using an embedding function, you can apply it to raw data
-    to generate embeddings for each record.
-
-    Say you have a pandas DataFrame with a `text` column that you want embedded,
-    you can use the `with_embeddings` function to generate embeddings and add them to 
-    an existing table.
-
-    ```python
-     import pandas as pd
-     from lancedb.embeddings import with_embeddings
-
-     df = pd.DataFrame(
-        [
-            {"text": "pepperoni"},
-            {"text": "pineapple"}

-     data = with_embeddings(embed_func, df)
-
-     # The output is used to create / append to a table
-     # db.create_table("my_table", data=data)
-    ```
-
-    If your data is in a different column, you can specify the `column` kwarg to `with_embeddings`.
-
-    By default, LanceDB calls the function with batches of 1000 rows. This can be configured
-    using the `batch_size` parameter to `with_embeddings`.
-
-    LanceDB automatically wraps the function with retry and rate-limit logic to ensure the OpenAI
-    API call is reliable.

-    At query time, you **must** use the same embedding function you used to vectorize your data.

-    space and the results will be nonsensical.

 ## 1. Define the embedding function
-We have some pre-defined embedding functions in the global registry, with more coming soon. Here's let's an implementation of CLIP as example.
-```
-registry = EmbeddingFunctionRegistry.get_instance()
-clip = registry.get("open-clip").create()

+    In the LanceDB python SDK, we define a global embedding function registry with
+    many different embedding models and even more coming soon. 
+    Here's let's an implementation of CLIP as example.
+

+    from lancedb.embeddings import get_registry
+
+    registry = get_registry()
+    clip = registry.get("open-clip").create()
+    ```
+
+    You can also define your own embedding function by implementing the `EmbeddingFunction` 
+    abstract base interface. It subclasses Pydantic Model which can be utilized to write complex schemas simply as we'll see next!
+
+=== "JavaScript""
+    In the TypeScript SDK, the choices are more limited. For now, only the OpenAI
+    embedding function is available.
+
+    ```javascript
+    const lancedb = require("vectordb");
+
+    // You need to provide an OpenAI API key
+    const apiKey = "sk-..."
+    // The embedding function will create embeddings for the 'text' column
+    const embedding = new lancedb.OpenAIEmbeddingFunction('text', apiKey)
+    ```
 
 ## 2. Define the data model or schema
-The embedding function defined above abstracts away all the details about the models and dimensions required to define the schema. You can simply set a field as **source** or **vector** column. Here's how:
 
-```python
+=== "Python"
-class Pets(LanceModel):
+    The embedding function defined above abstracts away all the details about the models and dimensions required to define the schema. You can simply set a field as **source** or **vector** column. Here's how:
+
+    ```python
+    class Pets(LanceModel):
         vector: Vector(clip.ndims) = clip.VectorField()
         image_uri: str = clip.SourceField()
-```
+    ```
 
-`VectorField` tells LanceDB to use the clip embedding function to generate query embeddings for the `vector` column and `SourceField` ensures that when adding data, we automatically use the specified embedding function to encode `image_uri`.
+    `VectorField` tells LanceDB to use the clip embedding function to generate query embeddings for the `vector` column and `SourceField` ensures that when adding data, we automatically use the specified embedding function to encode `image_uri`.
 
-## 3. Create LanceDB table
+=== "JavaScript"
-Now that we have chosen/defined our embedding function and the schema, we can create the table:
 
-```python
+    For the TypeScript SDK, a schema can be inferred from input data, or an explicit
-db = lancedb.connect("~/lancedb")
+    Arrow schema can be provided.
-table = db.create_table("pets", schema=Pets)
 
-```
+## 3. Create table and add data
 
-That's it! We've provided all the information needed to embed the source and query inputs. We can now forget about the model and dimension details and start to build our VectorDB pipeline.
+Now that we have chosen/defined our embedding function and the schema, 
+we can create the table and ingest data without needing to explicitly generate
+the embeddings at all:
 
-## 4. Ingest lots of data and query your table
+=== "Python"
-Any new or incoming data can just be added and it'll be vectorized automatically.
+    ```python
+    db = lancedb.connect("~/lancedb")
+    table = db.create_table("pets", schema=Pets)
 
-```python
+    table.add([{"image_uri": u} for u in uris])
-table.add([{"image_uri": u} for u in uris])
+    ```
-```
 
-Our OpenCLIP query embedding function supports querying via both text and images:
+=== "JavaScript"
 
-```python
+    ```javascript
-result = table.search("dog")
+    const db = await lancedb.connect("data/sample-lancedb");
-```
+    const data = [
+    { text: "pepperoni"},
+    { text: "pineapple"}
+    ]
 
-Let's query an image:
+    const table = await db.createTable("vectors", data, embedding)
+    ```
 
-```python
+## 4. Querying your table
-p = Path("path/to/images/samoyed_100.jpg")
+Not only can you forget about the embeddings during ingestion, you also don't
-query_image = Image.open(p)
+need to worry about it when you query the table:
-table.search(query_image)
+
-```
+=== "Python"
+
+    Our OpenCLIP query embedding function supports querying via both text and images:
+
+    ```python
+    results = (
+        table.search("dog")
+        .limit(10)
+        .to_pandas()

+    ```
+
+    Or we can search using an image:
+
+    ```python

+        table.search(query_image)
+        .limit(10)
+        .to_pandas()
+    )
+    ```

+    const results = await table
+    .search("What's the best pizza topping?")

Performance, latency and reliability are paramount to a vector DB, and building in Rust allows us to iterate and release updates more rapidly due to Rust’s safety guarantees. Both Lance (the data format) and LanceDB (the database) are written entirely in Rust. We also provide Python and JavaScript client libraries to interact with the database. Our Rust API is a little rough around the edges right now, but is fast becoming on par with the Python and JS APIs.

+    If you wish to specify an ordering field at query time, you must also

+    error will be raised that looks like `ValueError: The field does not exist: xxx`
+
+!!! note
+    The fields to sort on must be of typed unsigned integer, or else you will see 
+    an error during indexing that looks like 
+    `TypeError: argument 'value': 'float' object cannot be interpreted as an integer`.
+
+!!! note
+    You can specify multiple fields for ordering at indexing time.
+    But at query time only one ordering field is supported.
+
+
+## Phrase queries vs. terms queries
+
+For full-text search you can specify either a **phrase** query like `"the old man and the sea"`,
+or a **terms** search query like `"(Old AND Man) AND Sea"`. For more details on the terms
+query syntax, see Tantivy's [query parser rules](https://docs.rs/tantivy/latest/tantivy/query/struct.QueryParser.html).
+
+!!! tip "Note"
+    The query parser will raise an exception on queries that are ambiguous. For example, in the query `they could have been dogs OR cats`, `OR` is capitalized so it's considered a keyword query operator. But it's ambiguous how the left part should be treated. So if you submit this search query as is, you'll get `Syntax Error: they could have been dogs OR cats`.
+
+    ```py
+    # This raises a syntax error
+    table.search("they could have been dogs OR cats")
+    ```
+
+    On the other hand, lowercasing `OR` to `or` will work, because there are no capitalized logical operators and
+    the query is treated as a phrase query.
+
+    ```py
+    # This works!
+    table.search("they could have been dogs or cats")
+    ```
+
+It can be cumbersome to have to remember what will cause a syntax error depending on the type of
+query you want to perform. To make this simpler, when you want to perform a phrase query, you can
+enforce it in one of two ways:
+
+1. Place the double-quoted query inside single quotes. For example, `table.search('"they could have been dogs OR cats"')` is treated as
+a phrase query.
+2. Explicitly declare the `phrase_query()` method. This is useful when you have a phrase query that
+itself contains double quotes. For example, `table.search('the cats OR dogs were not really "pets" at all').phrase_query()`
+is treated as a phrase query.
+
+In general, a query that's declared as a phrase query will be wrapped in double quotes during parsing, with nested
+double quotes replaced by single quotes.

-LanceDB OSS uses the [object-store](https://docs.rs/object_store/latest/object_store/) Rust crate for object store access. There are general environment variables that can be used to configure the object store, such as the request timeout and proxy configuration. See the [object_store ClientConfigKey](https://docs.rs/object_store/latest/object_store/enum.ClientConfigKey.html) doc for available configuration options. The environment variables that can be set are the snake-cased versions of these variable names. For example, to set `ProxyUrl` use the environment variable `PROXY_URL`.

+
+    The `storage_options` parameter is only available in Python *async* API and JavaScript API.
+    It is not yet supported in the Python synchronous API.
+
+If you only want this to apply to one particular connection, you can pass the `storage_options` argument when opening the connection:
+

+
+    ```python
+    import lancedb

+
+!!! info "Storage option casing"
+
+    The storage option keys are case-insensitive. So `connect_timeout` and `CONNECT_TIMEOUT` are the same setting. Usually lowercase is used in the `storage_options` argument and uppercase is used for environment variables. In the `lancedb` Node package, the keys can also be provided in `camelCase` capitalization. For example, `connectTimeout` is equivalent to `connect_timeout`.

     When rows are updated, they are moved out of the index. The row will still show up in ANN queries, but the query will not be as fast as it would be if the row was in the index. If you update a large proportion of rows, consider rebuilding the index afterwards.
 
+## Consistency
+
+In LanceDB OSS, users can set the `read_consistency_interval` parameter on connections to achieve different levels of read consistency. This parameter determines how frequently the database synchronizes with the underlying storage system to check for updates made by other processes. If another process updates a table, the database will not see the changes until the next synchronization.
+
+There are three possible settings for `read_consistency_interval`:
+
+1. **Unset (default)**: The database does not check for updates to tables made by other processes. This provides the best query performance, but means that clients may not see the most up-to-date data. This setting is suitable for applications where the data does not change during the lifetime of the table reference.
+2. **Zero seconds (Strong consistency)**: The database checks for updates on every read. This provides the strongest consistency guarantees, ensuring that all clients see the latest committed data. However, it has the most overhead. This setting is suitable when consistency matters more than having high QPS.
+3. **Custom interval (Eventual consistency)**: The database checks for updates at a custom interval, such as every 5 seconds. This provides eventual consistency, allowing for some lag between write and read operations. Performance wise, this is a middle ground between strong consistency and no consistency check. This setting is suitable for applications where immediate consistency is not critical, but clients should see updated data eventually.
+
+!!! tip "Consistency in LanceDB Cloud"
+
+    This is only tune-able in LanceDB OSS. In LanceDB Cloud, readers are always eventually consistent.
+
+=== "Python"
+    
+    To set strong consistency, use `timedelta(0)`:
+
+    ```python
+    from datetime import timedelta
+    db = lancedb.connect("./.lancedb",. read_consistency_interval=timedelta(0))
+    table = db.open_table("my_table")
+    ```
+
+    For eventual consistency, use a custom `timedelta`:
+
+    ```python
+    from datetime import timedelta
+    db = lancedb.connect("./.lancedb", read_consistency_interval=timedelta(seconds=5))
+    table = db.open_table("my_table")
+    ```
+
+    By default, a `Table` will never check for updates from other writers. To manually check for updates you can use `checkout_latest`:
+
+    ```python
+    db = lancedb.connect("./.lancedb")
+    table = db.open_table("my_table")
+    
+    # (Other writes happen to my_table from another process)
+
+    # Check for updates
+    table.checkout_latest()
+    ```
+
+=== "JavaScript/Typescript"
+
+    To set strong consistency, use `0`:
+
+    ```javascript
+    const db = await lancedb.connect({ uri: "./.lancedb", readConsistencyInterval: 0 });
+    const table = await db.openTable("my_table");
+    ```
+
+    For eventual consistency, specify the update interval as seconds:
+
+    ```javascript
+    const db = await lancedb.connect({ uri: "./.lancedb", readConsistencyInterval: 5 });
+    const table = await db.openTable("my_table");

+# Hybrid Search
+
+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.
+
+## The challenge of (re)ranking search results
+Once you have a group of the most relevant search results from multiple search sources, you'd likely standardize the score and rank them accordingly. This process can also be seen as another independent step - reranking.
+There are two approaches for reranking search results from multiple sources.
+* <b>Score-based</b>: Calculate final relevance scores based on a weighted linear combination of individual search algorithm scores. Example - Weighted linear combination of semantic search & keyword-based search results.
+* <b>Relevance-based</b>: Discards the existing scores and calculates the relevance of each search result - query pair. Example - Cross Encoder models
+
+Even though there are many strategies for reranking search results, none works for all cases. Moreover, evaluating them itself is a challenge. Also, reranking can be dataset, application specific so it's hard to generalize.
+
+### Example evaluation of hybrid search with Reranking
+
+Here's some evaluation numbers from experiment comparing these re-rankers on about 800 queries. It is modified version of an evaluation script from [llama-index](https://github.com/run-llama/finetune-embedding/blob/main/evaluate.ipynb) that measures hit-rate at top-k.

+
+### Conclusion
+
+The results show that the reranking methods are able to improve the search results. However, the improvement is not consistent across all rerankers. The choice of reranker depends on the dataset and the application. It is also important to note that the reranking methods are not a replacement for the search methods. They are complementary and should be used together to get the best results. The speed to recall tradeoff is also an important factor to consider when choosing the reranker.

 ## Hybrid search in LanceDB
 You can perform hybrid search in LanceDB by combining the results of semantic and full-text search via a reranking algorithm of your choice. LanceDB provides multiple rerankers out of the box. However, you can always write a custom reranker if your use case need more sophisticated logic .

+# LanceDB JavaScript SDK
+
+A JavaScript library for [LanceDB](https://github.com/lancedb/lancedb).
+
+## Installation
+
+```bash
+npm install @lancedb/lancedb
+```
+
+This will download the appropriate native library for your platform. We currently
+support:
+
+- Linux (x86_64 and aarch64)
+- MacOS (Intel and ARM/M1/M2)
+- Windows (x86_64 only)
+
+We do not yet support musl-based Linux (such as Alpine Linux) or aarch64 Windows.
+
+## Usage
+
+### Basic Example
+
+```javascript
+import * as lancedb from "@lancedb/lancedb";
+const db = await lancedb.connect("data/sample-lancedb");
+const table = await db.createTable("my_table", [
+  { id: 1, vector: [0.1, 1.0], item: "foo", price: 10.0 },
+  { id: 2, vector: [3.9, 0.5], item: "bar", price: 20.0 },
+]);
+const results = await table.vectorSearch([0.1, 0.3]).limit(20).toArray();
+console.log(results);
+```
+
+The [quickstart](../basic.md) contains a more complete example.
+
+## Development
+
+```sh
+npm run build
+npm run test
+```
+
+### Running lint / format
+
+LanceDb uses eslint for linting. VSCode does not need any plugins to use eslint. However, it
+may need some additional configuration. Make sure that eslint.experimental.useFlatConfig is
+set to true. Also, if your vscode root folder is the repo root then you will need to set
+the eslint.workingDirectories to ["nodejs"]. To manually lint your code you can run:
+
+```sh
+npm run lint
+```
+
+LanceDb uses prettier for formatting. If you are using VSCode you will need to install the
+"Prettier - Code formatter" extension. You should then configure it to be the default formatter
+for typescript and you should enable format on save. To manually check your code's format you
+can run:
+
+```sh
+npm run chkformat
+```
+
+If you need to manually format your code you can run:
+
+```sh
+npx prettier --write .
+```
+
+### Generating docs
+
+```sh
+npm run docs
+
+cd ../docs
+# Asssume the virtual environment was created
+# python3 -m venv venv
+# pip install -r requirements.txt
+. ./venv/bin/activate

+# Class: Connection
+
+A LanceDB Connection that allows you to open tables and create new ones.
+
+Connection could be local against filesystem or remote against a server.
+
+A Connection is intended to be a long lived object and may hold open
+resources such as HTTP connection pools.  This is generally fine and
+a single connection should be shared if it is going to be used many
+times. However, if you are finished with a connection, you may call
+close to eagerly free these resources.  Any call to a Connection
+method after it has been closed will result in an error.
+
+Closing a connection is optional.  Connections will automatically
+be closed when they are garbage collected.
+
+Any created tables are independent and will continue to work even if
+the underlying connection has been closed.

+
+## Methods
+
+### btree
+
+▸ **btree**(): [`Index`](Index.md)
+
+Create a btree index
+
+A btree index is an index on a scalar columns.  The index stores a copy of the column
+in sorted order.  A header entry is created for each block of rows (currently the
+block size is fixed at 4096).  These header entries are stored in a separate
+cacheable structure (a btree).  To search for data the header is used to determine
+which blocks need to be read from disk.
+
+For example, a btree index in a table with 1Bi rows requires sizeof(Scalar) * 256Ki
+bytes of memory and will generally need to read sizeof(Scalar) * 4096 bytes to find
+the correct row ids.
+
+This index is good for scalar columns with mostly distinct values and does best when
+the query is highly selective.
+
+The btree index does not currently have any parameters though parameters such as the
+block size may be added in the future.
+
+#### Returns
+
+[`Index`](Index.md)

+
+___
+
+### ivfPq
+
+▸ **ivfPq**(`options?`): [`Index`](Index.md)
+
+Create an IvfPq index
+
+This index stores a compressed (quantized) copy of every vector.  These vectors
+are grouped into partitions of similar vectors.  Each partition keeps track of
+a centroid which is the average value of all vectors in the group.
+
+During a query the centroids are compared with the query vector to find the closest
+partitions.  The compressed vectors in these partitions are then searched to find
+the closest vectors.
+
+The compression scheme is called product quantization.  Each vector is divided into
+subvectors and then each subvector is quantized into a small number of bits.  the
+parameters `num_bits` and `num_subvectors` control this process, providing a tradeoff
+between index size (and thus search speed) and index accuracy.
+
+The partitioning process is called IVF and the `num_partitions` parameter controls how
+many groups to create.
+
+Note that training an IVF PQ index on a large dataset is a slow operation and
+currently is also a memory intensive operation.

+
+### nearestTo
+
+▸ **nearestTo**(`vector`): [`VectorQuery`](VectorQuery.md)
+
+Find the nearest vectors to the given query vector.
+
+This converts the query from a plain query to a vector query.
+
+This method will attempt to convert the input to the query vector
+expected by the embedding model.  If the input cannot be converted
+then an error will be thrown.
+
+By default, there is no embedding model, and the input should be
+an array-like object of numbers (something that can be used as input
+to Float32Array.from)
+
+If there is only one vector column (a column whose data type is a
+fixed size list of floats) then the column does not need to be specified.
+If there is more than one vector column you must use
+
+#### Parameters
+
+| Name | Type |
+| :------ | :------ |
+| `vector` | `unknown` |
+
+#### Returns
+
+[`VectorQuery`](VectorQuery.md)
+
+**`See`**
+
+ - [VectorQuery#column](VectorQuery.md#column)  to specify which column you would like
+to compare with.
+
+If no index has been created on the vector column then a vector query
+will perform a distance comparison between the query vector and every
+vector in the database and then sort the results.  This is sometimes
+called a "flat search"
+
+For small databases, with a few hundred thousand vectors or less, this can
+be reasonably fast.  In larger databases you should create a vector index
+on the column.  If there is a vector index then an "approximate" nearest
+neighbor search (frequently called an ANN search) will be performed.  This
+search is much faster, but the results will be approximate.
+
+The query can be further parameterized using the returned builder.  There
+are various ANN search parameters that will let you fine tune your recall
+accuracy vs search latency.
+
+Vector searches always have a `limit`.  If `limit` has not been called then
+a default `limit` of 10 will be used.

+
+___
+
+### select
+
+▸ **select**(`columns`): [`Query`](Query.md)
+
+Return only the specified columns.
+
+By default a query will return all columns from the table.  However, this can have
+a very significant impact on latency.  LanceDb stores data in a columnar fashion.  This
+means we can finely tune our I/O to select exactly the columns we need.
+
+As a best practice you should always limit queries to the columns that you need.  If you
+pass in an array of column names then only those columns will be returned.
+
+You can also use this method to create new "dynamic" columns based on your existing columns.
+For example, you may not care about "a" or "b" but instead simply want "a + b".  This is often
+seen in the SELECT clause of an SQL query (e.g. `SELECT a+b FROM my_table`).
+
+To create dynamic columns you can pass in a Map<string, string>.  A column will be returned
+for each entry in the map.  The key provides the name of the column.  The value is
+an SQL string used to specify how the column is calculated.
+
+For example, an SQL query might state `SELECT a + b AS combined, c`.  The equivalent
+input to this method would be:
+
+#### Parameters
+
+| Name | Type |
+| :------ | :------ |
+| `columns` | `string`[] \| `Record`\<`string`, `string`\> \| `Map`\<`string`, `string`\> |
+
+#### Returns
+
+[`Query`](Query.md)
+
+**`Example`**
+
+```ts
+new Map([["combined", "a + b"], ["c", "c"]])
+
+Columns will always be returned in the order given, even if that order is different than
+the order used when adding the data.
+
+Note that you can pass in a `Record<string, string>` (e.g. an object literal). This method
+uses `Object.entries` which should preserve the insertion order of the object.  However,
+object insertion order is easy to get wrong and `Map` is more foolproof.

+# Class: Table
+
+A Table is a collection of Records in a LanceDB Database.
+
+A Table object is expected to be long lived and reused for multiple operations.
+Table objects will cache a certain amount of index data in memory.  This cache
+will be freed when the Table is garbage collected.  To eagerly free the cache you
+can call the `close` method.  Once the Table is closed, it cannot be used for any
+further operations.
+
+Closing a table is optional.  It not closed, it will be closed when it is garbage
+collected.

+
+___
+
+### checkout
+
+▸ **checkout**(`version`): `Promise`\<`void`\>
+
+Checks out a specific version of the Table
+
+Any read operation on the table will now access the data at the checked out version.
+As a consequence, calling this method will disable any read consistency interval
+that was previously set.
+
+This is a read-only operation that turns the table into a sort of "view"
+or "detached head".  Other table instances will not be affected.  To make the change
+permanent you can use the `[Self::restore]` method.
+
+Any operation that modifies the table will fail while the table is in a checked
+out state.
+
+To return the table to a normal state use `[Self::checkout_latest]`
+
+#### Parameters

+
+### query
+
+▸ **query**(): [`Query`](Query.md)
+
+Create a [Query](Query.md) Builder.
+
+Queries allow you to search your existing data.  By default the query will
+return all the data in the table in no particular order.  The builder
+returned by this method can be used to control the query using filtering,
+vector similarity, sorting, and more.
+
+Note: By default, all columns are returned.  For best performance, you should
+only fetch the columns you need.  See [`Query::select_with_projection`] for
+more details.
+
+When appropriate, various indices and statistics based pruning will be used to
+accelerate the query.
+
+#### Returns
+
+[`Query`](Query.md)
+
+A builder that can be used to parameterize the query
+
+**`Example`**
+
+```ts
+// SQL-style filtering
+//
+// This query will return up to 1000 rows whose value in the `id` column
+// is greater than 5.  LanceDb supports a broad set of filtering functions.
+for await (const batch of table.query()
+                         .filter("id > 1").select(["id"]).limit(20)) {
+ console.log(batch);
+}
+```
+
+**`Example`**
+
+```ts
+// Vector Similarity Search
+//
+// This example will find the 10 rows whose value in the "vector" column are
+// closest to the query vector [1.0, 2.0, 3.0].  If an index has been created
+// on the "vector" column then this will perform an ANN search.
+//
+// The `refine_factor` and `nprobes` methods are used to control the recall /
+// latency tradeoff of the search.
+for await (const batch of table.query()
+                   .nearestTo([1, 2, 3])
+                   .refineFactor(5).nprobe(10)
+                   .limit(10)) {
+ console.log(batch);
+}
+```
+
+**`Example`**
+
+```ts
+// Scan the full dataset
+//
+// This query will return everything in the table in no particular order.
+for await (const batch of table.query()) {
+  console.log(batch);
+}
+```

+
+### restore
+
+▸ **restore**(): `Promise`\<`void`\>
+
+Restore the table to the currently checked out version
+
+This operation will fail if checkout has not been called previously
+
+This operation will overwrite the latest version of the table with a
+previous version.  Any changes made since the checked out version will
+no longer be visible.
+
+Once the operation concludes the table will no longer be in a checked
+out state and the read_consistency_interval, if any, will apply.

+
+### update
+
+▸ **update**(`updates`, `options?`): `Promise`\<`void`\>
+
+Update existing records in the Table
+
+An update operation can be used to adjust existing values.  Use the
+returned builder to specify which columns to update.  The new value
+can be a literal value (e.g. replacing nulls with some default value)
+or an expression applied to the old value (e.g. incrementing a value)
+
+An optional condition can be specified (e.g. "only update if the old
+value is 0")
+
+Note: if your condition is something like "some_id_column == 7" and
+you are updating many rows (with different ids) then you will get
+better performance with a single [`merge_insert`] call instead of
+repeatedly calilng this method.
+
+#### Parameters
+
+| Name | Type | Description |
+| :------ | :------ | :------ |
+| `updates` | `Record`\<`string`, `string`\> \| `Map`\<`string`, `string`\> | the columns to update Keys in the map should specify the name of the column to update. Values in the map provide the new value of the column. These can be SQL literal strings (e.g. "7" or "'foo'") or they can be expressions based on the row being updated (e.g. "my_col + 1") |
+| `options?` | `Partial`\<[`UpdateOptions`](../interfaces/UpdateOptions.md)\> | additional options to control the update behavior |

+### vectorSearch
+
+▸ **vectorSearch**(`vector`): [`VectorQuery`](VectorQuery.md)
+
+Search the table with a given query vector.
+
+This is a convenience method for preparing a vector query and
+is the same thing as calling `nearestTo` on the builder returned
+by `query`.

+
+### version
+
+▸ **version**(): `Promise`\<`number`\>
+
+Retrieve the version of the table
+
+LanceDb supports versioning.  Every operation that modifies the table increases
+version.  As long as a version hasn't been deleted you can `[Self::checkout]` that
+version to view the data at that point.  In addition, you can `[Self::restore]` the
+version to replace the current table with a previous version.

+
+### nprobes
+
+▸ **nprobes**(`nprobes`): [`VectorQuery`](VectorQuery.md)
+
+Set the number of partitions to search (probe)
+
+This argument is only used when the vector column has an IVF PQ index.
+If there is no index then this value is ignored.
+
+The IVF stage of IVF PQ divides the input into partitions (clusters) of
+related values.
+
+The partition whose centroids are closest to the query vector will be
+exhaustiely searched to find matches.  This parameter controls how many
+partitions should be searched.
+
+Increasing this value will increase the recall of your query but will
+also increase the latency of your query.  The default value is 20.  This
+default is good for many cases but the best value to use will depend on
+your data and the recall that you need to achieve.
+
+For best results we recommend tuning this parameter with a benchmark against
+your actual data to find the smallest possible value that will still give
+you the desired recall.
+
+#### Parameters

+
+### postfilter
+
+▸ **postfilter**(): [`VectorQuery`](VectorQuery.md)
+
+If this is called then filtering will happen after the vector search instead of
+before.
+
+By default filtering will be performed before the vector search.  This is how
+filtering is typically understood to work.  This prefilter step does add some
+additional latency.  Creating a scalar index on the filter column(s) can
+often improve this latency.  However, sometimes a filter is too complex or scalar
+indices cannot be applied to the column.  In these cases postfiltering can be
+used instead of prefiltering to improve latency.
+
+Post filtering applies the filter to the results of the vector search.  This means
+we only run the filter on a much smaller set of data.  However, it can cause the
+query to return fewer than `limit` results (or even no results) if none of the nearest
+results match the filter.
+
+Post filtering happens during the "refine stage" (described in more detail in
+
+#### Returns
+
+[`VectorQuery`](VectorQuery.md)
+
+**`See`**
+
+[VectorQuery#refineFactor](VectorQuery.md#refinefactor)).  This means that setting a higher refine
+factor can often help restore some of the results lost by post filtering.
+
+#### Defined in
+
+[query.ts:307](https://github.com/lancedb/lancedb/blob/9d178c7/nodejs/lancedb/query.ts#L307)
+
+___
+
+### refineFactor
+
+▸ **refineFactor**(`refineFactor`): [`VectorQuery`](VectorQuery.md)
+
+A multiplier to control how many additional rows are taken during the refine step
+
+This argument is only used when the vector column has an IVF PQ index.
+If there is no index then this value is ignored.
+
+An IVF PQ index stores compressed (quantized) values.  They query vector is compared
+against these values and, since they are compressed, the comparison is inaccurate.
+
+This parameter can be used to refine the results.  It can improve both improve recall
+and correct the ordering of the nearest results.
+
+To refine results LanceDb will first perform an ANN search to find the nearest
+`limit` * `refine_factor` results.  In other words, if `refine_factor` is 3 and
+`limit` is the default (10) then the first 30 results will be selected.  LanceDb
+then fetches the full, uncompressed, values for these 30 results.  The results are
+then reordered by the true distance and only the nearest 10 are kept.
+
+Note: there is a difference between calling this method with a value of 1 and never
+calling this method at all.  Calling this method with any value will have an impact
+on your search latency.  When you call this method with a `refine_factor` of 1 then
+LanceDb still needs to fetch the full, uncompressed, values so that it can potentially
+reorder the results.
+
+Note: if this method is NOT called then the distances returned in the _distance column
+will be approximate distances based on the comparison of the quantized query vector
+and the quantized result vectors.  This can be considerably different than the true
+distance between the query vector and the actual uncompressed vector.
+
+#### Parameters

+___
+
+### select
+
+▸ **select**(`columns`): [`VectorQuery`](VectorQuery.md)
+
+Return only the specified columns.
+
+By default a query will return all columns from the table.  However, this can have
+a very significant impact on latency.  LanceDb stores data in a columnar fashion.  This
+means we can finely tune our I/O to select exactly the columns we need.
+
+As a best practice you should always limit queries to the columns that you need.  If you
+pass in an array of column names then only those columns will be returned.
+
+You can also use this method to create new "dynamic" columns based on your existing columns.
+For example, you may not care about "a" or "b" but instead simply want "a + b".  This is often
+seen in the SELECT clause of an SQL query (e.g. `SELECT a+b FROM my_table`).
+
+To create dynamic columns you can pass in a Map<string, string>.  A column will be returned
+for each entry in the map.  The key provides the name of the column.  The value is
+an SQL string used to specify how the column is calculated.
+
+For example, an SQL query might state `SELECT a + b AS combined, c`.  The equivalent
+input to this method would be:
+
+#### Parameters
+
+| Name | Type |
+| :------ | :------ |
+| `columns` | `string`[] \| `Record`\<`string`, `string`\> \| `Map`\<`string`, `string`\> |
+
+#### Returns
+
+[`VectorQuery`](VectorQuery.md)
+
+**`Example`**
+
+```ts
+new Map([["combined", "a + b"], ["c", "c"]])
+
+Columns will always be returned in the order given, even if that order is different than
+the order used when adding the data.
+
+Note that you can pass in a `Record<string, string>` (e.g. an object literal). This method
+uses `Object.entries` which should preserve the insertion order of the object.  However,
+object insertion order is easy to get wrong and `Map` is more foolproof.

+Distance type to use to build the index.
+
+Default value is "l2".
+
+This is used when training the index to calculate the IVF partitions
+(vectors are grouped in partitions with similar vectors according to this
+distance type) and to calculate a subvector's code during quantization.
+
+The distance type used to train an index MUST match the distance type used
+to search the index.  Failure to do so will yield inaccurate results.
+
+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].
+
+Note: the cosine distance is undefined when one (or both) of the vectors
+are all zeros (there is no direction).  These vectors are invalid and may
+never be returned from a vector search.
+
+"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.

+### maxIterations
+
+• `Optional` **maxIterations**: `number`
+
+Max iteration to train IVF kmeans.
+
+When training an IVF PQ 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 these extra
+iterations have diminishing returns.
+
+The default value is 50.

+### numPartitions
+
+• `Optional` **numPartitions**: `number`
+
+The number of IVF partitions to create.
+
+This value should generally scale with the number of rows in the dataset.
+By default the number of partitions is the square root of the number of
+rows.
+
+If this value is too large then the first part of the search (picking the
+right partition) will be slow.  If this value is too small then the second
+part of the search (searching within a partition) will be slow.

+
+### numSubVectors
+
+• `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
+
+• `Optional` **sampleRate**: `number`
+
+The number of vectors, per partition, to sample when training IVF kmeans.
+
+When an IVF PQ 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.
+
+The default value is 256.

+### makeArrowTable
+
+▸ **makeArrowTable**(`data`, `options?`): `ArrowTable`
+
+An enhanced version of the makeTable function from Apache Arrow
+that supports nested fields and embeddings columns.
+
+(typically you do not need to call this function.  It will be called automatically
+when creating a table or adding data to it)
+
+This function converts an array of Record<String, any> (row-major JS objects)
+to an Arrow Table (a columnar structure)
+
+Note that it currently does not support nulls.
+
+If a schema is provided then it will be used to determine the resulting array
+types.  Fields will also be reordered to fit the order defined by the schema.
+
+If a schema is not provided then the types will be inferred and the field order
+will be controlled by the order of properties in the first record.  If a type
+is inferred it will always be nullable.
+
+If the input is empty then a schema must be provided to create an empty table.
+
+When a schema is not specified then data types will be inferred.  The inference
+rules are as follows:
+
+ - boolean => Bool
+ - number => Float64
+ - String => Utf8
+ - Buffer => Binary
+ - Record<String, any> => Struct
+ - Array<any> => List
+
+#### Parameters
+
+| Name | Type |
+| :------ | :------ |
+| `data` | `Record`\<`string`, `unknown`\>[] |
+| `options?` | `Partial`\<[`MakeArrowTableOptions`](classes/MakeArrowTableOptions.md)\> |
+
+#### Returns
+
+`ArrowTable`
+
+**`Example`**
+
+```ts
+import { fromTableToBuffer, makeArrowTable } from "../arrow";
+import { Field, FixedSizeList, Float16, Float32, Int32, Schema } from "apache-arrow";
+
+const schema = new Schema([
+  new Field("a", new Int32()),
+  new Field("b", new Float32()),
+  new Field("c", new FixedSizeList(3, new Field("item", new Float16()))),
+ ]);
+ const table = makeArrowTable([
+   { a: 1, b: 2, c: [1, 2, 3] },
+   { a: 4, b: 5, c: [4, 5, 6] },
+   { a: 7, b: 8, c: [7, 8, 9] },
+ ], { schema });
+```
+
+By default it assumes that the column named `vector` is a vector column
+and it will be converted into a fixed size list array of type float32.
+The `vectorColumns` option can be used to support other vector column
+names and data types.
+
+```ts
+
+const schema = new Schema([
+   new Field("a", new Float64()),
+   new Field("b", new Float64()),
+   new Field(
+     "vector",
+     new FixedSizeList(3, new Field("item", new Float32()))
+   ),
+ ]);
+ const table = makeArrowTable([
+   { a: 1, b: 2, vector: [1, 2, 3] },
+   { a: 4, b: 5, vector: [4, 5, 6] },
+   { a: 7, b: 8, vector: [7, 8, 9] },
+ ]);
+ assert.deepEqual(table.schema, schema);
+```
+
+You can specify the vector column types and names using the options as well
+
+```typescript
+
+const schema = new Schema([
+   new Field('a', new Float64()),
+   new Field('b', new Float64()),
+   new Field('vec1', new FixedSizeList(3, new Field('item', new Float16()))),
+   new Field('vec2', new FixedSizeList(3, new Field('item', new Float16())))
+ ]);
+const table = makeArrowTable([
+   { a: 1, b: 2, vec1: [1, 2, 3], vec2: [2, 4, 6] },
+   { a: 4, b: 5, vec1: [4, 5, 6], vec2: [8, 10, 12] },
+   { a: 7, b: 8, vec1: [7, 8, 9], vec2: [14, 16, 18] }
+ ], {
+   vectorColumns: {
+     vec1: { type: new Float16() },
+     vec2: { type: new Float16() }
+   }
+ }
+assert.deepEqual(table.schema, schema)
+```

+# Rust-backed Client Migration Guide
+
+In an effort to ensure all clients have the same set of capabilities we have begun migrating the
+python and node clients onto a common Rust base library. In python, this new client is part of
+the same lancedb package, exposed as an asynchronous client. Once the asynchronous client has
+reached full functionality we will begin migrating the synchronous library to be a thin wrapper
+around the asynchronous client.
+
+This guide describes the differences between the two APIs and will hopefully assist users
+that would like to migrate to the new API.
+
+## Closeable Connections
+
+The Connection now has a `close` method. You can call this when
+you are done with the connection to eagerly free resources. Currently
+this is limited to freeing/closing the HTTP connection for remote
+connections. In the future we may add caching or other resources to
+native connections so this is probably a good practice even if you
+aren't using remote connections.
+
+In addition, the connection can be used as a context manager which may
+be a more convenient way to ensure the connection is closed.
+
+```python
+import lancedb
+
+async def my_async_fn():
+    with await lancedb.connect_async("my_uri") as db:
+        print(await db.table_names())
+```
+
+It is not mandatory to call the `close` method. If you do not call it
+then the connection will be closed when the object is garbage collected.
+
+## Closeable Table
+
+The Table now also has a `close` method, similar to the connection. This
+can be used to eagerly free the cache used by a Table object. Similar to
+the connection, it can be used as a context manager and it is not mandatory
+to call the `close` method.
+
+### Changes to Table APIs
+
+- Previously `Table.schema` was a property. Now it is an async method.
+- The method `Table.__len__` was removed and `len(table)` will no longer
+  work. Use `Table.count_rows` instead.
+
+### Creating Indices
+
+The `Table.create_index` method is now used for creating both vector indices
+and scalar indices. It currently requires a column name to be specified (the
+column to index). Vector index defaults are now smarter and scale better with
+the size of the data.
+
+To specify index configuration details you will need to specify which kind of
+index you are using.
+
+### Querying
+
+The `Table.search` method has been renamed to `AsyncTable.vector_search` for
+clarity.
+
+## Features not yet supported
+
+The following features are not yet supported by the asynchronous API. However,
+we plan to support them soon.
+
+- You cannot specify an embedding function when creating or opening a table.
+  You must calculate embeddings yourself if using the asynchronous API
+- The merge insert operation is not supported in the asynchronous API
+- Cleanup / compact / optimize indices are not supported in the asynchronous API
+- add / alter columns is not supported in the asynchronous API
+- The asynchronous API does not yet support any full text search or reranking
+  search
+- Remote connections to LanceDb Cloud are not yet supported.
+- The method Table.head is not yet supported.
