Joris Van den Bossche commented on ARROW-12359:
-----------------------------------------------
I forgot to comment about this before, but being able to append (on those
filesystems that support it) _might_ be useful for when creating an
fsspec-compatible filesystem wrapper around our filesystems (which eg will be
needed if fsspec wants to continue to have HDFS support,
https://github.com/intake/filesystem_spec/issues/663).
(now, I didn't look in enough detail to know if it's actually needed. And such
a wrapper filesystem will always be able to raise an error that a certain
operation is not supported, of course).
