+ Read a table from ORC format
+
+ Parameters
+ ----------
+ source : str, pyarrow.NativeFile, or file-like object
+ If a string passed, can be a single file name or directory name. For
+ file-like objects, only read a single file. Use pyarrow.BufferReader to
+ read a file contained in a bytes or buffer-like object.
+ columns : list
+ If not None, only these columns will be read from the file. A column
+ name may be a prefix of a nested field, e.g. 'a' will select 'a.b',
+ 'a.c', and 'a.d.e'. If empty, no columns will be read. Note
+ that the table will still have the correct num_rows set despite having
+ no columns.
Review comment:
Hmm, it's maybe better to leave it for a separate JIRA, as reading in
all columns to then select none of them in a second step might be a bit
surprising for users?
