Hi, My colleague has informed me that during the Arrow 12->15 upgrade, he found that writing a pandas Dataframe with datetime64[ns] to parquet will result in nanosecond metadata and nanosecond values.
I wonder if this is something configurable to the old behavior so we can enable “nanosecond in parquet” gradually? There are code that reads parquet files that don’t handle parquet nanosecond now. Thanks! Li
