>
> Iceberg's planFiles() API is very expensive because it involves reading the
> Avro manifest files. It's especially expensive on object stores, though
> manifest caching can help here.
> Currently we invoke this API two times during table loading (via
> IcebergUtil.getIcebergFiles()), once in loadAllPartition() and once in
> loadPartitionStats().
> We should just invoke IcebergUtil.getIcebergFiles() once, then pass the
> result object to loadAllPartition() and loadPartitionStats().
