Accessing Unity Catalog's MLFlow model registry from outside Databricks

Hello Everyone

We are integrating Unity Catalog in our Organisation's Databricks. In our case we are planning to move our inference from Databricks to Kubernetes. In order to make the inference code use the latest registered model we need to query the model registry from outside Databricks. So I wanted to ask:
1. Is the model registry exposed via a public api?

2. If not how can we do this?

Thanks in advance for your time.

Hey @rahuja

If you register your models in Unity Catalog (and they effectively appear on your Catalog Explorer) you could use Delta sharing for your models. https://docs.databricks.com/en/data-sharing/index.html 

Also, curious about the decision. Databricks serving capabilities are quite good, what are the benefits that you are looking for with this migration?

Hello @mhiltner 

Currently we are contemplating whether to do this or not. In my organisation this decision is based due to cost. We already have a managed Kubernetes cluster that we are paying for.

I have used glue in the past to score models that are registered in Databricks mlflow registry. You need to configure MLFlow on Kubernetes to access your model registry.
You can use something like this -
