Weston Pace commented on ARROW-1009:
------------------------------------
I think this is completed at this point. There are asynchronous versions of
the various record batch readers. There is not an AsyncRecordBatchReader
though. RecordBatchReader is basically Iterator<RecordBatch> + GetMetadata().
There has not been the need for a similar interface on the async side.
Generally the schema is either passed along with the reader or it is grabbed
from the FileReader. I'm not sure we need to do anything here any more.
