> I have a little question is that when will a user want to delete stats of some partitions rather than whole table, just curious This is mainly related to the statistics of partition granularity. partition statistics is mainly used for queries that contain partitions. This statistics is more useful if the partition statistics involved can be used instead of all other partition statistics. In addition, we can also collect statistics incrementally by partition, etc. Coming back to your question, I feel that partition statistics may need to be removed in this scenario. For example, a table has been collected statistics, but the partition time is a long time ago, then you can delete this "expired" partition statistics separately. Also, if the partition data is changed, then it's statistics is invalid and can be deleted. Of course, there are other ways to solve similar problems, if not necessary, it can be removed. -- This is an automated message from the Apache Git Service.
