Thanks, that got me further:
```py
pq.write_table(row, parquet_filepath)
File "lib/python3.11/site-packages/pyarrow/parquet/core.py", line 3106, in
write_table
writer.write_table(table, row_group_size=row_group_size)
File "lib/python3.11/site-packages/pyarrow/parquet/core.py", line 1092, in
write_table
self.writer.write_table(table, row_group_size=row_group_size)
File "pyarrow/_parquet.pyx", line 1777, in
pyarrow._parquet.ParquetWriter.write_table
File "pyarrow/error.pxi", line 100, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: Casting from timestamp[ns, tz=UTC] to
timestamp[us] would lose data: 1692809086
```
