Description
Currently, there's a lot of template params that could easily become runtime parameter. Every template param causes the need to compile more instantiations. If we reduce template params, we will improve compile time and binary size.
- Pairwise distances distance metric arg
- ANN filter type (make polymorphic)
- Reduce CAGRA / CAGRA-Q templates (make more runtime hyper-params)
@tfeher @divyegala @achirkin @benfred please add to this list as opportunities arise.

Research direction
The issue identifies pairwise-distance metrics, the ANN filter type, and CAGRA/CAGRA-Q templates as starting areas; no files or tests are named. Locate those entry points first, then determine which parameters can become runtime values. Done means reducing the selected template parameters while improving compile time and binary size.
