Pierre updated ARROW-10061:
---------------------------
Description:
Hi,
I am sorry, this is a simple usage question, that I raised on
[SO|https://stackoverflow.com/questions/63991411/how-to-convert-a-float-to-a-parquet-timestamp-logical-type],
but got no answer.
I came across the [Parquet Logical Types documentation
page|https://github.com/apache/parquet-format/blob/master/LogicalTypes.md] on
Github, and more specifically the chapter regarding
[Timestamp|https://github.com/apache/parquet-format/blob/master/LogicalTypes.md#timestamp].
Please, how can we convert a column of timestamps stored as float64 to a column
with timestamps stored as `TIMESTAMP` parquet logical type?
For instance, starting with this code.
{code:python}
import pyarrow as pa
my_table = pa.table({'timestamp': pa.array([1600419000.477,1600419001.027])})
{code}
Thanks for any help,
Have a good day,
Bests,
Pierre
