No. I think we can complete the partition split and merge functions through temporary partitions. For example, we create a temporary partition and import the partition data that needs to be merged into this new temporary partition. When the data is imported, replace the previous partitions with this partition. In the same way, partition split can also be achieved through this mechanism. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
