@joyhaldar is correct here if you check the plan you'll see exactly what he
is mentioning
> +- *(1) Filter (isnotnull(dep) AND **file_path LIKE
warehouse/iceberg/goodX_facts/fact1X_table/% ESCAPE 'X'**)
> +- *(1) ColumnarToRow
> +- BatchScan testhadoop.default.table[id, salary, dep]
testhadoop.default.table (branch=null) [filters=file_path IS NOT NULL,
groupedBy=] RuntimeFilters: []
Which means in SparkScanBuilder, the only predicate we are given in ```
public Predicate[] pushPredicates(Predicate[] predicates) {```
Is `dep is NOT NULL`
The key thing to notice here, is if you don't see a predicate in the
"BatchScan" entry, it means the Iceberg Library doesn't see it
