Hi James! Batch re-ranking is intended for use when you have a very large number of queries (e.g., many thousands of queries). For those, it amortizes a lot of the costs and has a very high throughput.
I believe you're using batch mode because of limited memory. In that case, any solution that involves loading the index from memory will be slow because it has to hit the disk (I assume you're not using an SSD?). In that case, an approach that selectively loads vectors might indeed help, but only for the unusual applications where you have a very small number of queries to run.
