Milvus connection
Use the Milvus connection to store and confirm the accuracy of your credentials and connection details to access a Milvus vector store.
Milvus is a vector database that is built for scalable similarity search. You can use the Milvus connection to connect to the Milvus service inside IBM watsonx.data. Alternatively, you can connect to a stand-alone Milvus instance that you provision yourself.
Supported versions for stand-alone Milvus
If you provision your own instance of Milvus, the supported versions are v2.4.0-PreGA and later.
Prerequisite to connect to a Milvus instance in watsonx.data
Use the watsonx.data console to provision a Milvus instance in watsonx.data:
- watsonx.data on IBM Cloud: Adding Milvus service.
- watsonx.data on Cloud Pak for Data (on-prem). Follow the same steps as for watsonx.data stand-alone: Adding a Milvus service.
- watsonx.data stand-alone: Adding a Milvus service.
