Spark's fast-write path still relies on the table-level `coreOptions.bucket()` setting rather than routing based on partition-to-bucket mappings; this can lead to errors or data being written to the incorrect bucket when partitions have varying bucket counts. The documentation itself acknowledges a risk of data corruption—an issue that cannot be mitigated simply by following usage guidelines. Another edge case arises in `PartitionEntry.merge`: when creation times are identical, the logic defaults to the larger bucket count, potentially causing the old layout to be retained during downscaling operations. -- This is an automated message from the Apache Git Service.
