30 seconds googling from my side:
This is what is called under-the-hood:`psql.read_sql(sql, con=conn,
params=parameters, **kwargs)` -> what I see is that Pandas string gets
converted to Timestamp (and I guess pandas uses pyarrow for that). But pandas
has native Timstamp object `pd.Timestamp('20180310')` so I guess you should
utilize that.
You seem to be using an implicit conversion of Pandas that is happening in
this case.
But those are all guesses - I have no experience with either of the
technologies, just googled it. But for me it looks like it's not snowflake
provider that depends on `pyarrow` but your queries implicitly do, so nothing
to do in provider really - if you want to write queries and use implicit
dependency on Pyarrow, then you need to declare it as dependency yourself.
