import { PyConnect, TsConnect, RsConnect, PyConnectEnterprisePlaceholders, TsConnectEnterprisePlaceholders, RsConnectEnterprisePlaceholders } from '/snippets/connection.mdx';
import { PyQuickstartData, PyQuickstartCreateTable, PyQuickstartAddData, PyQuickstartVectorSearch1, TsQuickstartData, TsQuickstartCreateTable, TsQuickstartAddData, TsQuickstartVectorSearch1, RsQuickstartDefineStruct, RsQuickstartData, RsQuickstartCreateTable, RsQuickstartAddData, RsQuickstartVectorSearch1 } from '/snippets/quickstart.mdx';
This quickstart uses a local database and works without an account or API key.
Follow the steps below, or jump to the [complete examples](#code) to copy a runnable program.
## 1\. Install LanceDB {#1-install-lancedb}
Choose your language. Python uses Polars to display the search results. TypeScript needs Node.js 22.18 or later to run the `.mts` example directly.
```bash Python (pip) icon="python"
pip install lancedb polars
```
```bash Python (uv) icon="python"
uv venv
uv pip install lancedb polars
```
```bash TypeScript icon="square-js"
npm install @lancedb/lancedb
```
```bash Rust icon="rust"
cargo init --name lancedb_quickstart
cargo add lancedb@0.31.0 --features polars,remote
cargo add tokio --features macros,rt-multi-thread
```
Run the Rust commands in a new, empty directory. The `polars` feature provides DataFrame output; `remote` also lets this example connect to Enterprise.
### Python pre-release builds {#python-pre-release-builds}
To pick up the latest features and bug fixes
before the next stable release, install a pre-release from LanceDB's Fury index.
```bash Python (pip) icon="terminal"
pip install --pre --extra-index-url https://pypi.fury.io/lancedb/ lancedb
```
```bash Python (uv) icon="terminal"
uv venv
uv pip install --prerelease allow --index https://pypi.fury.io/lancedb/ lancedb
# To add to pyproject.toml, use:
uv add --prerelease allow --index https://pypi.fury.io/lancedb/ lancedb
```
Pre-release builds receive the same level of testing as stable releases, but their availability is not guaranteed
for more than 6 months after release. For real-world workloads, we recommend you use the latest stable release
as far as possible.
### Older x86_64 CPUs {#older-x86-cpus}
The default `lancedb` wheel targets `x86-64-haswell` (AVX2 + FMA + F16C). On older x86_64 CPUs without AVX2
(Intel Sandy Bridge, Ivy Bridge, Westmere; AMD Bulldozer, Piledriver, Steamroller), `import lancedb` crashes
with `Illegal instruction`.
Install `lancedb-compat` instead. It exposes the same API (`import lancedb` still works), is built at the
`x86-64-v2` baseline, and uses runtime SIMD dispatch to still use AVX2, FMA, or AVX-512 when available:
```bash Python (pip) icon="terminal"
pip install lancedb-compat
```
The two packages share the same `lancedb/` namespace and conflict at install time, so pick one. To switch,
uninstall the other first (`pip uninstall lancedb && pip install lancedb-compat`).
## 2\. Connect to a database {#2-connect-to-a-lancedb-database}
### Use a local directory {#connect-via-local-directory-path}
LanceDB creates an `ex_lancedb` directory to store your tables. No server is needed.
{PyConnect}
{"import * as lancedb from \"@lancedb/lancedb\";\n\n"}
{TsConnect}
{"use lancedb::connect;\n\n"}
{RsConnect}
The [complete examples](#code) include the imports and entry points for each language. For Python's async API, see [Connecting to a database](/basics/connect).
### Connect to LanceDB Enterprise {#connect-to-lancedb-enterprise}
Use the database URI, API key, and endpoint provided by your administrator or the LanceDB team. Replace the placeholders below with those details. Use the deployment's region if provided; otherwise keep `us-east-1`.
{PyConnectEnterprisePlaceholders}
{"import * as lancedb from \"@lancedb/lancedb\";\n\n"}
{TsConnectEnterprisePlaceholders}
{"use lancedb::connect;\n\n"}
{RsConnectEnterprisePlaceholders}
In application code, load credentials from environment variables or a secrets manager. See [connection settings](/basics/connect#enterprise) for an example.
Need a deployment? [Contact the LanceDB team](https://www.lancedb.com/contact). For differences between local and server execution, see [Moving to LanceDB Enterprise](/basics/sdk#moving-to-enterprise).
### Connect via object storage URIs {#connect-via-object-storage-uris}
Use an `s3://`, `gs://`, or `az://` URI in place of the local path. See [Configuring storage](/deployment/storage) for credentials and provider-specific options.
## 3\. Create a table and add data {#3-create-a-new-table}
Each row describes a character and stores a vector alongside their name, description, and stats.
These vectors are made up for this example. In your application, use an embedding model to generate vectors from your data.
{PyQuickstartData}
{TsQuickstartData}
{RsQuickstartDefineStruct}
{RsQuickstartData}
Create a `characters` table from those records:
{PyQuickstartCreateTable}
{TsQuickstartCreateTable}
{RsQuickstartCreateTable}
This example uses overwrite mode so you can run it again. It replaces any existing `characters` table in the database you connect to.
Add one more character:
{PyQuickstartAddData}
{TsQuickstartAddData}
{RsQuickstartAddData}
## 4\. Search the table {#4-semantic-search}
Find the two vectors closest to the query vector. This example uses a fixed vector; it does not call an embedding model.
{PyQuickstartVectorSearch1}
{TsQuickstartVectorSearch1}
{RsQuickstartVectorSearch1}
Merlin and Morgana come back first. Python and Rust display a Polars DataFrame; TypeScript displays an array of results. The `_distance` column measures how far each result is from your query vector, with smaller values indicating a closer match.
## Complete examples {#code}
Each example below creates the local database, adds four characters, and prints the two closest matches. Use the dependencies from step 1.
Save this as `quickstart.py` and run `python quickstart.py`. If you installed with uv, run `uv run quickstart.py`.
{PyConnect}
{PyQuickstartData}
{PyQuickstartCreateTable}
{PyQuickstartAddData}
{PyQuickstartVectorSearch1}
Save this as `quickstart.mts` and run `node quickstart.mts` from the directory where you installed LanceDB.
{"import * as lancedb from \"@lancedb/lancedb\";\n\n"}
{TsConnect}
{TsQuickstartData}
{TsQuickstartCreateTable}
{TsQuickstartAddData}
{TsQuickstartVectorSearch1}
Replace `src/main.rs` with this program, then run `cargo run` from your project directory. The schema and Arrow conversion helpers are included.
{"use lancedb::connect;\n\n"}
{RsQuickstartDefineStruct}
{"\n#[tokio::main]\nasync fn main() -> Result<(), Box> {\n"}
{RsConnect}
{RsQuickstartData}
{RsQuickstartCreateTable}
{RsQuickstartAddData}
{RsQuickstartVectorSearch1}
{"\nOk(())\n}\n"}
## Next steps {#next-steps}
You've created a table, added rows, and searched it. Continue with the guides below.
