> Error: Table Schema does not match schema used to create file.
> The 0.11.1 release added these parameters to pyarrow.parquet.write_table(), but they are missing from pyarrow.parquet.ParquetWriter.write_table().. I'm seeing mismatches between the table schema and the file schema, but they are identical in the error message with modified: timestamp[ms] column types in both schemas. The only thing which looks odd is the Pandas metadata that has a modified column with a panda datatype of datetime and a numpy datatype of datetime64[ns]
