 When using LanceDB OSS, you can choose where to store your data. The tradeoffs between storage options are covered in the [storage architecture guide](/storage). This page shows how to configure each backend.

+Supported keys include `secret_id`, `secret_key`, `region`, and `endpoint`. You can also authenticate via the `TENCENTCLOUD_SECRET_ID` and `TENCENTCLOUD_SECRET_KEY` environment variables.

+**Availability**
+
+COS is bundled in the Python wheel by default. To use it from Rust or the Node binding, build with the `cos` Cargo feature enabled.

+## GooseFS
+
+[GooseFS](https://www.tencentcloud.com/document/product/1424) is Tencent Cloud's distributed cache acceleration layer for COS and S3. It is a common choice when the same hot dataset is read repeatedly, such as vector search and AI training workloads. Connect using the `goosefs://` URI scheme.

+GooseFS reads credentials and endpoint configuration from the GooseFS client environment. See the [GooseFS documentation](https://www.tencentcloud.com/document/product/1424) for cluster setup.

+LanceDB is one of the few vector databases built on modular, disk-first components. That design makes it flexible enough to run across local NVMe, EBS, EFS, and any object store that exposes an S3-compatible API. It also supports region-specific backends such as [Tencent COS](/storage/configuration#tencent-cos) and cache-acceleration layers such as [GooseFS](/storage/configuration#goosefs).
 
 Choosing a backend is a balance between latency, scalability, cost, and operational complexity. Use this guide to pick the right fit for your workload.
