Polars + Omna vs Weaviate

Weaviate is a full vector database. Omna is a method on your DataFrame. For analytical workloads where the data already lives in Polars, the DataFrame method usually wins on latency and operational cost.

The API

df.omna.search("query", top_k=5)

Use Weaviate when

· You need hybrid (BM25 + vector) search at scale · You need GraphQL APIs · You serve external users

Use Omna when

· The data is already in Polars/Pandas · You want zero containers · You can't send data off-host
