Rick Cobb updated ARROW-6813:
-----------------------------
Comment: was deleted
(was: As I looked more deeply at the issue, it appears that 0.15.0 completely
reworks the notion of header parsing, and the most straightforward solution is
to remove the `headers` option from the Ruby layer. Thus my PR. We've
"repaired" our application code by removing the use of the option; we always
had it set to `true` anyway, and that's the behavior with no options now.)
