[jira] [Created] (ARROW-5895) [Python] New version stores
timestamps as epoch ms instead of ISO timestamp string
John Wilson created ARROW-5895:
----------------------------------
Summary: [Python] New version stores timestamps as epoch ms instead of ISO timestamp string
Key: ARROW-5895
URL: https://issues.apache.org/jira/browse/ARROW-5895
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.14.0
Environment: Linux dev.office.whoop.com 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Reporter: John Wilson
Just upgraded from pyarrow 0.13 to 0.14.
Columns of type TimestampType(timestmap[ns]) now get written as epoch ms values:
1561939200507
Where 0.13 wrote TimestampType(timestamp[ns]) as an ISO string:
2019-07-01T00:00:00.507Z
This broke my implementation. How do I get pyarrow to write ISO strings again in 0.14?
Here is my table write:
{{ pyarrow.parquet.write_to_dataset(table=tbl, root_path=local_path,}}
{{ partition_cols=['env', 'dt'],}}
{{ coerce_timestamps='ms',}}
{{ allow_truncated_timestamps=True,}}
{{ version='2.0',}}
{{ compression='SNAPPY')}}
