The Best Way to Use Text Embeddings Portably Is with Parquet and Polars
For another library that has great performance and features like full text indexing and the ability to version changes I’d recommend lancedb https://lancedb.github.io/lancedb/
Yes, it’s a vector database and has more complexity. But you can use it without creating indexes and it has excellent polars and pandas zero copy arrow support also.
