As part of exploring the Arrow C++ implementation, I wrote standalone tool for streaming Arrow to a file from CSV, using the new CSV parser implementation from [~pitrou]. I realize that Arrow's emphasis is on in-memory representation, as opposed to efficient storage to disk, so I'd love to know if this has any utility for the project. At the very least, it seems like a quick way to get into exploring the format from a something easily inspectable/familiar (i.e., CSV).
In either case, I'm making this issue here as a placeholder for an accompanying PR on Github. Also, I think this is my first issue for this project, so please let me know if I should do anything differently.
PR is now available at: https://github.com/apache/arrow/pull/3136
