Parameters ---------- source : str, pyarrow.NativeFile, or file-like object If a string passed, can be a single file 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'. Output always follows the ordering of the file and not the `columns` list. If empty, no columns will be read. Note that the table will still have the correct num_rows set despite having no columns. filesystem : FileSystem, default None If nothing passed, will be inferred based on path. Path will try to be found in the local on-disk filesystem otherwise it will be parsed as an URI to determine the filesystem. rnrorprqrrrsrtrurvrwc [U[5(a[R"S[SS9 Xp[ UUUUUUUUU U U U S9 n U R U5 SSS5 g!,(df  g=f)NzThe order of the arguments has changed.
