imay commented on issue #2663: [Proposal] Support partition overwrite operation URL: https://github.com/apache/incubator-doris/issues/2663#issuecomment-584179072 > I mean, for example, the origin partition(p1, p2) ranges are: > [0, 10) > [10, 20) > > And user create 2 temp partitions (tp1, tp2) with range: > [10, 11) and [15, 18) > > And user replace the (p1, p2) with (tp1, tp2), should we allow this operation? > > Two options. First, we check strictly. The range must be covered and equal. But if user really want to new range of tp1 and tp2? So the second option is, we only check for conflicts and not for coverage. Oh I see. My concern is that Doris should not allow the existence of holes at this time. If there is a hole, it may cause problems in other modules. So I am more inclined to check if it is covered. For the problem you said, then you need the user to create another 3 placeholders partition tp3 [0, 10), tp4 [11, 15), tp5 [18, 20). In this case, we can make the user operate successfully.
