Description

I encountered this working on ARROW-459 – while we have the ability to write and read record batches, the schema/metadata parts of the file and stream reader/writer implementations are not complete. I did a bit of work on it in my patch for ARROW-459 but gave up as I realized there was more work to do than made sense for that patch (which is for dictionary-encoded data).
