What I want to emphasize is not how to deal with temporary partitions during split and merge. I want to emphasize that we can also complete the functions of partition split and merge through temporary partitions. So what I mean is that we should not assume that it is related to an existing partition when doing temporary partitioning. Currently we can just generate from other partitions, but this premise should not be made. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
