   > Sync -> exception and Async -> no exception is easy enough to remember (although tricky to implement it seems). Do you think there are any utilities we could add to futures to make that easier?
   
   I think the existing utilities (combined with the implicit Future(Status) constructor) do a good enough job. Also, it's isolated to the Parquet codebase, so I'm not too worried about exceptions. The changes were less about exceptions per se and more about just disentangling the I/O from the footer logic so we could make it sync/async as needed.
