Hi,
The Date64 type is a source of common confusion for myself and the
community and I wonder if someone might be able to shed some light on
its purpose.
In particular:
- It cannot be round-tripped through parquet
- It is unclear how it is different from Timestamp(TimeUnit::Millisecond)
- Does it represent the quantity 2020-03-19 00:00:00 or 2020-03-19, i.e.
without the time
- What should be done if the value is not divisible by number of
milliseconds in a day
Any clarifications would be most appreciated.
Kind Regards,
Raphael
