#OpenSource #DevTools #LLM

Kicking off 2026 with Rust Delhi Meetup #12, and what a way to start. Thanks to Guinnes Singh for accepting my talk proposal & being a great host throughout.

I presented on building incremental data pipelines with @cocoindex.bsky.social, a framework I've been contributing towards.

(1/n)

@cocoindex.bsky.social has a Rust-powered execution engine with Python bindings,so you get the performance without leaving Python. @agriyakhetarp.al was the one who told me about Rust Delhi in the first place, so glad I didn't skip this one.

The meetup was at Aftershoot's office (great dogfooding)!

AI agents understand codebases 🤖

CocoIndex: real-time semantic code indexing

→ Tree-sitter chunking
→ Incremental
→ Vector search
Use:
• MCP for AI editors
• Semantic search
• AI code review
• Auto docs

Query "Find auth" → instant code chunks
