> @bowenliang123 @ConeyLiu i understand REBALANCE_PARTITIONS_BY_COL this adds a adaptive coalesce(AQE) which just coalesces the partitions local to executor( hence reducing number of files written) . Is this effective if the partitions are spread across different workers since the partitions wont be local anymore( for coalesce to work) ? <img width="427" alt="image" src="https://github.com/apache/iceberg/assets/1935105/04947fd7-425c-4253-a20e-eaddf46afdbe"> Since RebalancePartitions is introduced, a shuffle read stage was introduced. So I think it works for partitions across worker nodes. -- This is an automated message from the Apache Git Service.
