> It's not easy to do -- you wouldn't know up front that the application will do KNN searching at all. And, maybe only certain vectors in the `.vec` will ever be accessed and so you need to pay that long random access price to find and cache just those ones. I'm trying to understand this sentence: * it should be a one-liner using `setPreload` to preload "*.vec" if we wanted to do it either from FSDirectory.open or by default in MMapDirectory * if the application isn't doing KNN searching then they won't have .vec? I struggle to imagine someone indexing a ton of "extra" vectors that isnt "using" them and hasn't noticed big performance impact -- This is an automated message from the Apache Git Service.
