   > I don't think we could build exec plans on top of this because exec plans 
assume the input doesn't fit in memory which is not possible with chunked 
arrays.
   
   I mean the VectorKernel interface for chunked arrays could be a streaming 
interface such as:
   ```c++
     virtual Result<std::shared_ptr<ArrayVector>> ConsumeChunks(const 
ArrayVector&) = 0;
     virtual Result<std::shared_ptr<ArrayVector>> Finish() = 0;
   ```
