manishmalhotrawork edited a comment on issue #280: Add persistent IDs to partition fields URL: https://github.com/apache/incubator-iceberg/issues/280#issuecomment-524733183 @rdblue thanks for the answer. Curios on the flow and as how fieldId are maintained in PartitionSpec vs Table Schema. Here [PartitionSpec is initialized](https://github.com/apache/incubator-iceberg/blob/master/api/src/main/java/org/apache/iceberg/PartitionSpec.java#L63) And fields are copied to partition spec, which also included original IDs assigned to fields. and in [partitionType method](https://github.com/apache/incubator-iceberg/blob/master/api/src/main/java/org/apache/iceberg/PartitionSpec.java#L113) where new fieldID is assigned ( 1000+) for the partitionFields and returns StructType with those fields. Not sure if Im missing something. So, why original fieldId and ids assigned in `partitionSpec` are different ? How the `partitionSpec` returned `StructType` with IDs as 1000+ is used?
