@agrawalreetika Why is IcebergPartition class needed? I see it adds a name field but that field is not used. HIveSplit has List<HivePartitionKey> partitionKeys;, and the HivePartitionKey is very similar to this IcebergPartition. So I assume you want to introduce a similar class to HivePartitionKey so we can serialize the split, is this right? If this is the case, 1) it should not be named IcebergPartition but IcebergPartitionKey. 2) the content is the same as HivePartitionKey. I think we can use use HivePartitionKey in IcebergSplit directly.
