----------------------------------
Summary: [Python] Provide an option to convert on
coerce_timestamps instead of error
Key: ARROW-2555
URL: https://issues.apache.org/jira/browse/ARROW-2555
Project: Apache Arrow
Issue Type: Improvement
Components: Python
Reporter: Uwe L. Korn
Fix For: 0.10.0
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.
