Nanosecond Precision

if isinstance(timestamp, timedelta) or isinstance(timestamp, datetime):

It seems that python client not support insert of nanosecond precision, I try to use standard timestamp precision and found out that it doesn't support nanoseconds precision to achieve that I use pandas, it seems your client depends on standard one and its cut off nanoseconds precision.

Maybe this not the case (I am not experienced in Python) but I can't write down pandas timestamp with nanosecond precision into client.

Thanks,

Hi @dkasianov,

thanks for using our client.

The Python's datetime doesn't support precision with nanoseconds so the library during writes and queries ignores everything after microseconds.

If you would like to use datetime with nanosecond precision you should use pandas.Timestamp that is replacement for python datetime.datetime object and also you should set a proper DateTimeHelper to the client.
