Resolution: Duplicate
Duplicate of ARROW-5878
> [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
> Priority: Major
>
> 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')}}
