Feature Registry App

# 🚀 Feature Registry Application

This is a modern web application that allows users to interact with the Databricks Feature Registry. The app provides a user-friendly interface for exploring existing features in Unity Catalog. Additionally, users can generate code for creating feature specs and training sets to train machine learning models and deploy features as Feature Serving Endpoints.

## ✨ Features

- 🔍 List and search for features in Unity Catalog
- 🔒 On-behalf-of-user authentication
- ⚙️ Code-gen for creating feature specs and training sets
- 📋 Configurable catalog allow-listing for access control

## 🏗️ Architecture

The application is built with:
- 🌟 **Streamlit** for the UI
- 🧱 **Databricks SDK** for interacting with Unity Catalog

## 🔑 Requirements

The application requires the following scopes:
- `catalog.catalogs:read`
- `catalog.schemas:read`
- `catalog.tables:read`

The app owner needs to grant other users `Can Use` permission for the app itself, along with access to the underlying Databricks resources.
