Module 4 – Code deep dive
You have witnessed the system in action—covering everything from preprocessing and embedding to uploading and searching vector data and metadata on-chain.
In this module, we will dive deeper into the architecture and implementation. You will discover how the Rell backend integrates with the Vector DB extension, how we store full movie metadata alongside vectors, and how the Python client interacts with your Chromia chain.
We will walk through the actual code used in the demo while highlighting areas where the design offers flexibility, allowing you to adapt it to suit your specific use case.
