Upsert and dedup tables rely on partitioning by primary key so that all records of a key land on the same partition/server. Changing the partition column, function, or number of partitions can break that routing invariant and cause duplicates or wrong query results. Add a backward-incompatibility check in TableConfigUtils.validateBackwardCompatibility that rejects any segmentPartitionConfig change (added, removed, or modified) on a table that is upsert/dedup enabled, mirroring the existing upsert/dedup config-update checks. Like the other checks it can be bypassed with a force update. -- This is an automated message from the Apache Git Service.
