-## How to delete rows from a table
-
-Use the `delete()` method on tables to delete rows from a table. To choose
-which rows to delete, provide a filter that matches on the metadata columns.
-This can delete any number of rows that match the filter.
-
-=== "Python"
-      ```python
-      tbl.delete('item = "fizz"')

-
-=== "Javascript"
-      ```javascript
-      await tbl.delete('item = "fizz"')
-      ```
-
-The deletion predicate is a SQL expression that supports the same expressions
-as the `where()` clause on a search. They can be as simple or complex as needed.
-To see what expressions are supported, see the [SQL filters](sql.md) section.

-## How to remove a table
-
-Use the `drop_table()` method on the database to remove a table.
-
-=== "Python"
-      ```python
-      db.drop_table("my_table")
-      ```
-
-This permanently removes the table and is not recoverable, unlike deleting rows.
-By default, if the table does not exist an exception is raised. To suppress this,
-you can pass in `ignore_missing=True`.

 LanceDB supports many additional features when creating indices to speed up search and options for search.
 These are contained in the next section of the documentation.

-## Development
-
-First, rename `.env.example` to `.env.local`, and fill out `OPENAI_API_KEY` with your OpenAI API key. You can get one [here](https://openai.com/blog/openai-api).
-
-Run the development server:
-
-```bash
-npm run dev
-# or
-yarn dev
-# or
-pnpm dev
-```
-
-Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
-
-This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
-
-## Learn More
-
-To learn more about LanceDB or Next.js, take a look at the following resources:
-
-- [LanceDB Documentation](https://lancedb.github.io/lancedb/) - learn about LanceDB, the developer-friendly serverless vector database.
-- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
-- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
-
-## LanceDB on Next.js and Vercel
-
-FYI: these configurations have been pre-implemented in this template.
-
-Since LanceDB contains a prebuilt Node binary, you must configure `next.config.js` to exclude it from webpack. This is required for both using Next.js and deploying on Vercel.
-```js
-/** @type {import('next').NextConfig} */
-module.exports = ({
-  webpack(config) {
-    config.externals.push({ vectordb: 'vectordb' })
-    return config;
-  }
-})
-```
-
-To deploy on Vercel, we need to make sure that the NodeJS runtime static file analysis for Vercel can find the binary, since LanceDB uses dynamic imports by default. We can do this by modifying `package.json` in the `scripts` section.
-```json
-{
-  ...
-  "scripts": {
-    ...
-    "vercel-build": "sed -i 's/nativeLib = require(`@lancedb\\/vectordb-\\${currentTarget()}`);/nativeLib = require(`@lancedb\\/vectordb-linux-x64-gnu`);/' node_modules/vectordb/native.js && next build",

-A Table is a collection of Records in a LanceDB Database. You can follow along on colab!
-
-## Creating a LanceDB Table
-
-=== "Python"
-    ### LanceDB Connection
-
-    ```python
-    import lancedb
-    db = lancedb.connect("./.lancedb")
-    ```
-
-    LanceDB allows ingesting data from various sources - `dict`, `list[dict]`, `pd.DataFrame`, `pa.Table` or a `Iterator[pa.RecordBatch]`. Let's take a look at some of the these.
-
-    ### From list of tuples or dictionaries
-
-    ```python
-    import lancedb
-
-    db = lancedb.connect("./.lancedb")
-
-    data = [{"vector": [1.1, 1.2], "lat": 45.5, "long": -122.7},
-            {"vector": [0.2, 1.8], "lat": 40.1, "long": -74.1}]
-
-    db.create_table("my_table", data)
-
-    db["my_table"].head()
-    ```
-
-    !!! info "Note"
-        If the table already exists, LanceDB will raise an error by default. If you want to overwrite the table, you can pass in mode="overwrite" to the createTable function.
-
-        ```python
-        db.create_table("name", data, mode="overwrite")
-        ```
-
-
-    ### From pandas DataFrame
-
-    ```python
-    import pandas as pd
-
-    data = pd.DataFrame({
-        "vector": [[1.1, 1.2], [0.2, 1.8]],
-        "lat": [45.5, 40.1],
-        "long": [-122.7, -74.1]
-    })
-
-    db.create_table("table2", data)
-
-    db["table2"].head()
-    ```
-    !!! info "Note"
-        Data is converted to Arrow before being written to disk. For maximum control over how data is saved, either provide the PyArrow schema to convert to or else provide a PyArrow Table directly.
-
-    ```python
-    custom_schema = pa.schema([
-    pa.field("vector", pa.list_(pa.float32(), 2)),
-    pa.field("lat", pa.float32()),
-    pa.field("long", pa.float32())
-    ])
-
-    table = db.create_table("table3", data, schema=custom_schema)
-    ```
-
-    ### From PyArrow Tables
-    You can also create LanceDB tables directly from pyarrow tables
-
-    ```python
-    table = pa.Table.from_arrays(
-            [
-                pa.array([[3.1, 4.1], [5.9, 26.5]],
-                        pa.list_(pa.float32(), 2)),
-                pa.array(["foo", "bar"]),
-                pa.array([10.0, 20.0]),
-            ],
-            ["vector", "item", "price"],
-        )
-
-    db = lancedb.connect("db")
-
-    tbl = db.create_table("test1", table)
-    ```
-
-    ### From Pydantic Models
-    LanceDB supports to create Apache Arrow Schema from a Pydantic BaseModel via pydantic_to_schema() method.
-
-    ```python
-    from lancedb.pydantic import Vector, LanceModel
-
-    class Content(LanceModel):
-        movie_id: int
-        vector: Vector(128)
-        genres: str
-        title: str
-        imdb_id: int
-
-        @property
-        def imdb_url(self) -> str:
-            return f"https://www.imdb.com/title/tt{self.imdb_id}"
-
-    import pyarrow as pa
-    db = lancedb.connect("~/.lancedb")
-    table_name = "movielens_small"
-    table = db.create_table(table_name, schema=Content)
-    ```
-
-    ### Using Iterators / Writing Large Datasets
-
-    It is recommended to use itertators to add large datasets in batches when creating your table in one go. This does not create multiple versions of your dataset unlike manually adding batches using `table.add()`
-
-    LanceDB additionally supports pyarrow's `RecordBatch` Iterators or other generators producing supported data types.
-
-    Here's an example using using `RecordBatch` iterator for creating tables.
-
-    ```python
-    import pyarrow as pa
-
-    def make_batches():
-        for i in range(5):
-            yield pa.RecordBatch.from_arrays(
-                [
-                    pa.array([[3.1, 4.1], [5.9, 26.5]],
-                            pa.list_(pa.float32(), 2)),
-                    pa.array(["foo", "bar"]),
-                    pa.array([10.0, 20.0]),
-                ],
-                ["vector", "item", "price"],
-            )
-
-    schema = pa.schema([
-        pa.field("vector", pa.list_(pa.float32(), 2)),
-        pa.field("item", pa.utf8()),
-        pa.field("price", pa.float32()),
-    ])
-
-    db.create_table("table4", make_batches(), schema=schema)
-    ```
-
-    You can also use iterators of other types like Pandas dataframe or Pylists directly in the above example.
-
-    ## Creating Empty Table
-    You can also create empty tables in python. Initialize it with schema and later ingest data into it.
-
-    ```python
-    import lancedb
-    import pyarrow as pa
-
-    schema = pa.schema(
-      [
-          pa.field("vector", pa.list_(pa.float32(), 2)),
-          pa.field("item", pa.string()),
-          pa.field("price", pa.float32()),
-      ])
-    tbl = db.create_table("table5", schema=schema)
-    data = [
-        {"vector": [3.1, 4.1], "item": "foo", "price": 10.0},
-        {"vector": [5.9, 26.5], "item": "bar", "price": 20.0},
-    ]
-    tbl.add(data=data)
-    ```
-
-    You can also use Pydantic to specify the schema
-
-    ```python
-    import lancedb
-    from lancedb.pydantic import LanceModel, vector
-
-    class Model(LanceModel):
-          vector: Vector(2)
-
-    tbl = db.create_table("table5", schema=Model.to_arrow_schema())
-    ```
-
-=== "Javascript/Typescript"
-
-    ### VectorDB Connection
-
-    ```javascript
-    const lancedb = require("vectordb");
-
-    const uri = "data/sample-lancedb";
-    const db = await lancedb.connect(uri);
-    ```
-
-    ### Creating a Table
-
-    You can create a LanceDB table in javascript using an array of records.
-
-    ```javascript
-    data
-    const tb = await db.createTable("my_table",
-                  data=[{"vector": [3.1, 4.1], "item": "foo", "price": 10.0},
-                        {"vector": [5.9, 26.5], "item": "bar", "price": 20.0}])
-    ```
-
-    !!! info "Note"
-    If the table already exists, LanceDB will raise an error by default. If you want to overwrite the table, you need to specify the `WriteMode` in the createTable function.
-
-    ```javascript
-    const table = await con.createTable(tableName, data, { writeMode: WriteMode.Overwrite })
-    ```
-
-## Open existing tables
-
-If you forget the name of your table, you can always get a listing of all table names:
-
-
-=== "Python"
-    ### Get a list of existing Tables
-
-    ```python
-    print(db.table_names())
-    ```
-=== "Javascript/Typescript"
-
-    ```javascript
-    console.log(await db.tableNames());
-    ```
-
-Then, you can open any existing tables
-
-=== "Python"
-
-    ```python
-    tbl = db.open_table("my_table")
-    ```
-=== "Javascript/Typescript"
-
-    ```javascript
-    const tbl = await db.openTable("my_table");
-    ```
-
-## Adding to a Table
-After a table has been created, you can always add more data to it using
-
-=== "Python"
-    You can add any of the valid data structures accepted by LanceDB table, i.e, `dict`, `list[dict]`, `pd.DataFrame`, or a `Iterator[pa.RecordBatch]`. Here are some examples.
-
-    ### Adding Pandas DataFrame
-
-    ```python
-    df = pd.DataFrame([{"vector": [1.3, 1.4], "item": "fizz", "price": 100.0},
-                  {"vector": [9.5, 56.2], "item": "buzz", "price": 200.0}])
-    tbl.add(df)
-    ```
-
-    You can also add a large dataset batch in one go using Iterator of any supported data types.
-
-    ### Adding to table using Iterator
-
-    ```python
-    import pandas as pd
-
-    def make_batches():
-        for i in range(5):
-            yield pd.DataFrame(
-                {
-                    "vector": [[3.1, 4.1], [1, 1]],
-                    "item": ["foo", "bar"],
-                    "price": [10.0, 20.0],
-                })
-
-    tbl.add(make_batches())
-    ```
-
-    The other arguments accepted:
-
-    | Name | Type | Description | Default |
-    |---|---|---|---|
-    | data | DATA | The data to insert into the table. | required |
-    | mode | str | The mode to use when writing the data. Valid values are "append" and "overwrite". | append |
-    | on_bad_vectors | str | What to do if any of the vectors are not the same size or contains NaNs. One of "error", "drop", "fill". | drop |
-    | fill value | float | The value to use when filling vectors: Only used if on_bad_vectors="fill". | 0.0 |
-
-
-=== "Javascript/Typescript"
-
-    ```javascript
-    await tbl.add([{vector: [1.3, 1.4], item: "fizz", price: 100.0},
-        {vector: [9.5, 56.2], item: "buzz", price: 200.0}])
-    ```
-
-## Deleting from a Table
-
-Use the `delete()` method on tables to delete rows from a table. To choose which rows to delete, provide a filter that matches on the metadata columns. This can delete any number of rows that match the filter.
-
-=== "Python"
-
-    ```python
-    tbl.delete('item = "fizz"')
-    ```
-
-    ### Deleting row with specific column value
-
-    ```python
-    import lancedb
-    import pandas as pd
-
-    data = pd.DataFrame({"x": [1, 2, 3], "vector": [[1, 2], [3, 4], [5, 6]]})
-    db = lancedb.connect("./.lancedb")
-    table = db.create_table("my_table", data)
-    table.to_pandas()
-    #   x      vector
-    # 0  1  [1.0, 2.0]
-    # 1  2  [3.0, 4.0]
-    # 2  3  [5.0, 6.0]
-
-    table.delete("x = 2")
-    table.to_pandas()
-    #   x      vector
-    # 0  1  [1.0, 2.0]
-    # 1  3  [5.0, 6.0]
-    ```
-
-    ### Delete from a list of values
-
-    ```python
-    to_remove = [1, 5]
-    to_remove = ", ".join(str(v) for v in to_remove)
-
-    table.delete(f"x IN ({to_remove})")
-    table.to_pandas()
-    #   x      vector
-    # 0  3  [5.0, 6.0]
-    ```
-
-=== "Javascript/Typescript"
-
-    ```javascript
-    await tbl.delete('item = "fizz"')
-    ```
-
-    ### Deleting row with specific column value
-
-    ```javascript
-    const con = await lancedb.connect("./.lancedb")
-    const data = [
-      {id: 1, vector: [1, 2]},
-      {id: 2, vector: [3, 4]},
-      {id: 3, vector: [5, 6]},
-    ];
-    const tbl = await con.createTable("my_table", data)
-    await tbl.delete("id = 2")
-    await tbl.countRows() // Returns 2
-    ```
-
-    ### Delete from a list of values
-
-    ```javascript
-    const to_remove = [1, 5];
-    await tbl.delete(`id IN (${to_remove.join(",")})`)
-    await tbl.countRows() // Returns 1

-Basic recipe
-____________
-
-The basic workflow to use LanceDB to create a similarity index on your FiftyOne
-datasets and use this to query your data is as follows:
-
-1)  Load a dataset into FiftyOne
-
-2)  Compute embedding vectors for samples or patches in your dataset, or select
-    a model to use to generate embeddings
-
-3)  Use the `compute_similarity()`
-    method to generate a LanceDB table for the samples or object
-    patches embeddings in a dataset by setting the parameter `backend="lancedb"` and
-    specifying a `brain_key` of your choice
-
-4)  Use this LanceDB table to query your data with
-    `sort_by_similarity()`
-
-5) If desired, delete the table
-
-The example below demonstrates this workflow.
-
-!!! Note
-
-    You must install the LanceDB Python client to run this
-    ```
-    pip install lancedb
-    ```
-
-```python
-
-import fiftyone as fo
-import fiftyone.brain as fob
-import fiftyone.zoo as foz
-
-# Step 1: Load your data into FiftyOne
-dataset = foz.load_zoo_dataset("quickstart")
-
-# Steps 2 and 3: Compute embeddings and create a similarity index
-lancedb_index = fob.compute_similarity(
-    dataset, 
-    model="clip-vit-base32-torch",
-    brain_key="lancedb_index",
-    backend="lancedb",
-)
-```
-Once the similarity index has been generated, we can query our data in FiftyOne
-by specifying the `brain_key`:
-
-```python
-# Step 4: Query your data
-query = dataset.first().id  # query by sample ID
-view = dataset.sort_by_similarity(
-    query, 
-    brain_key="lancedb_index",
-    k=10,  # limit to 10 most similar samples
-)
-
-# Step 5 (optional): Cleanup
-
-# Delete the LanceDB table
-lancedb_index.cleanup()
-
-# Delete run record from FiftyOne
-dataset.delete_brain_run("lancedb_index")
-```

 Delete rows from this table.
 
-This can be used to delete a single row, many rows, all rows, or
-sometimes no rows (if your predicate matches nothing).
-
-**`Examples`**
-
-```ts
-const con = await lancedb.connect("./.lancedb")
-const data = [
-   {id: 1, vector: [1, 2]},
-   {id: 2, vector: [3, 4]},
-   {id: 3, vector: [5, 6]},
-];
-const tbl = await con.createTable("my_table", data)
-await tbl.delete("id = 2")
-await tbl.countRows() // Returns 2
-```
-
-If you have a list of values to delete, you can combine them into a
-stringified list and use the `IN` operator:
-
-```ts
-const to_remove = [1, 5];
-await tbl.delete(`id IN (${to_remove.join(",")})`)
-await tbl.countRows() // Returns 1
-```
-
