morningman commented on issue #2663: [Proposal] Support partition overwrite operation URL: https://github.com/apache/incubator-doris/issues/2663#issuecomment-584151950 > Besides the ranges don't conflict, the new partitions' range should be exactly the same with old partitions'. For example in the situation that the old partitions ranges are [1,3), [3,5) the new partition is [1,2) [3,5), there will be a hole [2,3) in the table. I'm not sure if this will work fine. If so, we also need to be able to specify the name of corresponding formal partition for the temporary partition in the statement. This makes the statement more complicated. Maybe we can create a separate syntax for split and merge scenarios? Or simply use this flexible method directly and leave it to the user to judge and handle.
