Hey @aaryankumar1435-maker - thanks for your interest in adding a couchbase tutorial! The RAG functionality in Solace Agent Mesh is supported through the RAG plugin as described in the RAG Integration section of the agent mesh docs. This integration is supported through the plugins ecosystem and is defined in the Solace Agent Mesh core plugins repo.

Every vDB tech has its own configuration, and I can see couchbase fitting in this list there.

So I would recommend the following

1. Open a PR in the core plugins repo with support for couchbase in the RAG plugin
2. Reference the [Feature]: tutorial with using Couchbase as a vector database with Solace agent mesh #141 issue on that PR
3. We can then author a tutorial showing how to use and configure that plugin with solace agent mesh

I'll close this PR in favour of this process.

Let me know if you need help with this and I'd be happy to help out!
