Installation

To install this package, run the following command in your Node-RED user directory (typically ~/.node-red):

npm install @michael_ting/node-red-milvus

Usage

1. Drag the desired Milvus nodes from the palette into your flow.
2. Configure the Milvus Config node with the connection details of your Milvus instance.
3. Connect the nodes as needed and deploy your flow.

Example

Here is an example of how to use the Vector node to insert data into a Milvus collection:

1. Drag a Vector node into your flow.
2. Configure the Vector node with the collection name and method (insert).
3. Connect an Inject node to the Vector node to provide the data to be inserted.
4. Deploy the flow and trigger the Inject node to insert the data.
