surprised there’s no mention of kdb+ in here. iirc it’s older and more performant than most of these

kdb doesn't support effecient vector similarity searches, or efficient storage of high-dimensional vectors. It isn't really in the same class as the vector databases discussed in this post. It's more suited for time series data.
