Subject [jira] [Commented] (ARROW-100) [C++] Computing RowBatch size
Date Wed, 13 Apr 2016 02:36:25 GMT


Philipp Moritz commented on ARROW-100:


The implementation is here:

I'd like to write a test, is there any way to see how many bytes have been written to the
MemorySource? And is it enough to create a PR in git to contribute the code back?

> 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.
