<Icon name="Blocks" aria-hidden="true" /> [**Bundles**](/components-bundle-components) contain custom components that support specific third-party integrations with Langflow.

This page describes the components that are available in the **Milvus** bundle.

## Milvus vector store

The **Milvus** component reads and writes to Milvus vector stores using an instance of `Milvus` vector store.
