These vector values have internal buffers they use to return the vectors. In order to compare two vectors we need to use two independent sources so that one doesn't overwrite this internal state when fetching the second vector.
Sorry I forgot the second question and can't see it on my phone. Brb On Tue, Apr 18, 2023, 10:55 PM Jonathan Ellis <jbel...@gmail.com> wrote: > HI all, a couple questions on how HNSW works: > > 1.
