Proposal: Add Ollama-based NLP backend for computed fields

[kkhatke]

Hi team,

I wanted to propose adding support for a local Ollama-based NLP backend to enable natural-language computed fields.

Context

Currently, computed fields require manual SQL expressions. This proposal introduces an optional NLP layer that allows users to define computed fields using natural language, processed locally via Ollama.

Why this is useful

• Enables non-technical users to create computed fields easily
• Keeps everything local (no external API dependency)
• Aligns with the growing use of LLM-assisted data exploration

What’s implemented

I’ve already created a working implementation here:
#491

Key aspects:

• Local Ollama integration
• Translation of natural language → computed field expressions
• Designed to be optional and non-intrusive to existing workflows

Questions

• Would this align with the current roadmap?
• Would you prefer this as a plugin instead of core integration?
• Any preferred abstraction/interface for NLP backends?
• Happy to make any changes or adjustments based on feedback.

Thanks!
