[GitHub] [iceberg] singhpk234 opened a new issue #3978: [Spark] Handle caseSensitivity of runtimeFilters in runtimeFiltering Spark
singhpk234 opened a new issue #3978:
URL: https://github.com/apache/iceberg/issues/3978
Presently a query like this :
``` SQL
SELECT f.* FROM tableName f JOIN dim d ON f.Id = d.id AND f.Data = d.data AND d.date = DATE '1970-01-02'
```
fails with
> org.apache.iceberg.exceptions.ValidationException: Cannot find field 'Id' in struct: struct<1: id: optional long, 2: data: optional string, 3: date: optional date, 4: ts: optional timestamptz>
This happens because while creating inclusiveExpr from RuntimeFilters passed from Spark doesn't takes cares of case sensitivity : [CodePointer](https://github.com/apache/iceberg/blob/master/spark/v3.2/spark/src/main/java/org/apache/iceberg/spark/source/SparkBatchQueryScan.java#L171)
```java
Expression inclusiveExpr = Projections.inclusive(spec).project(runtimeFilterExpr);
```
As per my understanding we should pass ``Projections.inclusive(spec, caseSensitive())`` to make sure iceberg also interprets it in the same way as spark does. Post adding this check the above UT succeeds.
