Checking out Druid, looks fantastic. Does anyone have any experience with implementing a spacial index with around 200-300 dimensions? A Kd-tree is not efficient at such high dimensions, and I’m hoping someone has experience, or any ideas, enlightening me as to whether Druit will handle this type of query well.
Ideally, I’d like to say: “give me the top N documents within an X radius of some point”. Where that radius defines an N-dimensional sphere (N ~ 200).
Look forward to any advice!
