@pvary when working with metadata queries, the IO can be part of the Task, e.g.: https://github.com/apache/iceberg/blob/master/core/src/main/java/org/apache/iceberg/DataFilesTable.java#L139 If we remove the hadoop config from this IO to make the splits smaller, then we wouldn't be able to inject back the config later on the Tez worker-side, since the Task API does not provide any options for that. So I've disabled the serialization skipping for metadata queries. We can look into making this work for metadata queries as well in the future if the need arises, but I think that might require some Iceberg-side API changes too. -- This is an automated message from the Apache Git Service.
