> We consider the key and data lengths also even though the data is actually in
> off heap area. We should correct it.
> The impact will be at ScannerContext limit tracking where we use heapSize of
> cells to account the result size. So my proposal is to consider the cells
> length and heap size in Limit tracking and accounting. We have a
> maxResultSize which defaults to 2MB. When the sum of all cell's data size
> reaches 'maxResultSize' OR the sum of all cell's heap size reaches
> 'maxResultSize' , we need to send back the RPC response
