WebFeb 18, 2024 · Haversine should be using Ball trees, and not require the full distance matrix. However, depending on the data it is possible that the ball tree search can still end up using a bit of memory. Even so, it should fit in memory for most dataset sizes you suggest. Ultimately this is in the balltree creation / search phase, which is all in scikit-learn.
