I looked at adding things like decimal precision, expected precision, scale, etc. but those seem like individual column properties (more like schema) than a property of the Parquet reader. The timestamp conversion options seem to apply to the entire query. I meant all of those but I realize that this needs to be per column. We need to pass in `useDecimal128` and `useLegacyDateTimestampOrNTZ`at least unless we can access the SQLConf. The type promotion info can be derived in native, I think). -- This is an automated message from the Apache Git Service.
