Sounds good Philipp. I refined the title to avoid confusion.

> Hi,
> thank you guys for this project, I'm really enjoying what I've seen so far!
> There is an unimplemented method for getting the total size of objects:
> int64_t GetRowBatchSize(const RowBatch* batch);
> Has somebody already started to implement it or thought about how to do it?
> It could be done by recursively adding up all the involved buffer sizes, build the metadata and add its size. Let me know if you want me to create a draft of the implementation.
