• [I] Issue # placeholder: Support "selective execution" for kernels. This is IMO the most challenging part. As mentioned above, we need an incremental way to add selection-vector-aware kernels on demand, meanwhile accommodate legacy (selection-vector-non-aware) kernels to be executed "selection-vector-aware"-ly in a general manner. [arrow] via GitHub
• [I] Issue # placeholder: Move `scatter` function into compute core. As mentioned above, the `take` ("gather") and `scatter` functions play an essential role to support selective execution for arbitrary legacy (selection-vector-non-aware) kernels, thus they have to exist in libarrow. Function `take` already does. We need `scatter`. [arrow] via GitHub
