Checkout https://iceberg.apache.org/docs/latest/spark-ddl/#alter-table for how to re-order columns. >but it looks like rewriteManifests does not rewrite the metadata tree with the re-ordered partitions for older data - it only starts applying for new data - is the only way to make this apply for all historical data via the rewriteDataFiles Action? Yes if you want to rewrite past data with the updated partitioning you need to perform a rewriteDataFiles. This is because there are effectively new partition values that need to be computed. -- This is an automated message from the Apache Git Service.
