Having worked with Simon he knows his sh*t. We talked a lot about what the ideal search stack would look when we worked together at Shopify on search (him more infra, me more ML+relevance). I discussed how I just want a thing in the cloud to provide my retrieval arms, let me express ranking in a fluent "py-data" first way, and get out of my way
My ideal is that turbopuffer ultimately is like a Polars dataframe where all my ranking is expressed in my search API. I could just lazily express some lexical or embedding similarity, boost with various attributes like, maybe by recency, popularity, etc to get a first pass (again all just with dataframe math). Then compute features for a reranking model I run on my side - dataframe math - and it "just works" - runs all this as some kind of query execution DAG - and stays out of my way.
