Subject [jira] [Updated] (ARROW-100) Keeping track of final object sizes
Date Tue, 12 Apr 2016 23:21:25 GMT

     [ https://issues.apache.org/jira/browse/ARROW-100?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Philipp Moritz updated ARROW-100:
---------------------------------
    Description: 
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.

-- Philipp.
