Integrate Milvus (pymilvus) library
Hi @mariosasko，Just search randomly and I found this issue~ I'm the tech lead of Milvus and we are looking forward to integrate milvus together with huggingface datasets.

Any suggestion on how we could start?

Milvus is a popular open-source vector database. We should add a new vector index to support this project.
