Hi ,
I tried casting in `df.select`.
` let mut cast_df = df.select(fix_timestamp_to_micro(&sel_schema)).unwrap();`
and in the function.
```
fn fix_timestamp_to_micro(data_schema: &DFSchema) -> Vec<Expr> {
let mut exprs : Vec<Expr> = Vec::new();
for column in data_schema.fields() {
if column.data_type() == &DataType::Timestamp(TimeUnit::Nanosecond,
None) || column.data_type() == &DataType::Timestamp(TimeUnit::Microsecond,
None) {
let mut c = col(column.name());
let cast_expr = c.cast_to(
&DataType::Timestamp(TimeUnit::Microsecond, None), data_schema).unwrap();
exprs.push(cast_expr);
} else {
exprs.push(col(column.name()));
}
}
exprs
}
```
It didn't work. What I was also trying was to see if If I could place a
break point in delta-rs when the collect happened. What I tried to see was if
datafusion hit any delta-rs function when doing collect. I could not find any.
