@jeesou I see in the Iceberg metadata file the stats are generated. Example:
```
...
"statistics" : [ {
"snapshot-id" : 8936043009013447565,
"statistics-path" :
"s3://mybucket/datasets/temp/online_orders_ndv/metadata/c8c75f51-b30b-4214-9e84-47da6e5055c6-a24b38c2-c526-49fe-b5e0-7dd3c329b5ae.stat",
"file-size-in-bytes" : 28829,
"file-footer-size-in-bytes" : 272,
"blob-metadata" : [ {
"type" : "apache-datasketches-theta-v1",
"snapshot-id" : 8936043009013447565,
"sequence-number" : 1,
"fields" : [ 1 ],
"properties" : {
"ndv" : "98645980"
}
} ]
} ],
...
```
Anyway I do not see stats by running `DESC`:
```
spark.sql(f"""
DESCRIBE EXTENDED default.online_orders_ndv order_id
"""
).show(truncate=False)
```
Output:
```
+---------+----------+
|info_name|info_value|
+---------+----------+
|col_name |order_id |
|data_type|bigint |
|comment |NULL |
+---------+----------+
```
