hi @edmondop @jayzhan211 , I have a draft implementation for array_intersect, I use a hashmap to store the first array values and find values that appear in the hashmap. And it works just fine and looks like a general approach?

But I encounter a problem for Float32 and Float64, we can not just use HashMap<f32/f64> because std::hash::Hash is not implemented for float types, so I want to fix it by introducing ordered-float to make it hashable, is it too heavy for this case ?
Or do you have any better ideas to make it？ Very happy to see your advice ！

Perhaps you could use https://docs.rs/arrow-row/latest/arrow_row/? This would have the added benefit of supporting more complex types, e.g. lists of lists, and not adding additional codegen (#7988). The notes I wrote on #6981 (comment) might be helpful for this
