Two potential downsides to this approach: 1) the size taken by those temporary `ResolvedChunk`s is twice the size of indices, hence a bigger CPU cache footprint 2) there has to be a final "reverse resolution" step where we convert back the sorted `ResolvedChunk`s into absolute indices... or we maintain those absolute indices along the `ResolvedChunk`, which implies an ever bigger cache footprint Experimenting will tell whether this can be beneficial. -- This is an automated message from the Apache Git Service.
