> DPP has data issue when pruning on non-atomic type. for example:
> {noformat}
> spark.range(1000)
> .select(col("id"), col("id").as("k"))
> .write
> .partitionBy("k")
> .format("parquet")
> .mode("overwrite")
> .saveAsTable("df1");
> spark.range(100)
> .select(col("id"), col("id").as("k"))
> .write
> .partitionBy("k")
> .format("parquet")
> .mode("overwrite")
> .saveAsTable("df2")
> spark.sql("set spark.sql.optimizer.dynamicPartitionPruning.fallbackFilterRatio=2")
> spark.sql("set spark.sql.optimizer.dynamicPartitionPruning.reuseBroadcastOnly=false")
> spark.sql("SELECT df1.id, df2.k FROM df1 JOIN df2 ON struct(df1.k) = struct(df2.k) AND df2.id < 2").show
> {noformat}
> It should return two records, but it returns empty.
