> [Python] Provide an option to convert on coerce_timestamps instead of error
> ---------------------------------------------------------------------------

> Project: Apache Arrow

> At the moment, we error out on {{coerce_timestamps='ms'}} on
> {{pyarrow.parquet.write_table}} if the data contains a timestamp that would
> loose information when converted to milliseconds. In a lot of cases the user
> does not care about this granularity and rather wants the comfort
> functionality that the timestamp are stored regardlessly in Parquet. Thus we
> should provide an option to ignore the error and do the lossy conversion.
