> @j7nhai This is not related to Iceberg reader; rather, it's that Velox is
unable to handle your parquet file. Which engine wrote the iceberg table? I
have encountered this issue when reading timestamps written by StarRocks, where
the parquet timestamps written by SR lacked some information.
@liujiayi771
I wrote the iceberg table by spark-3.3 + iceberg-1.3.0. Here is the code I
created the test data.
```
spark-sql> CREATE TABLE timestamp_test (
> timestamp_col TIMESTAMP
> ) USING iceberg;
Time taken: 0.029 seconds
spark-sql>
> INSERT INTO timestamp_test VALUES (
> TIMESTAMP '2022-01-01 00:00:00'
> );
```
So the parquet file is created by iceberg. Maybe Velox is not able to handle
the parquet files created by iceberg with timestamp? Or there is something
wrong for substrait? I don't have any debugging idea right now.
