[GitHub] [incubator-doris] weihongkai2008 opened a new issue #5556: In some cases, be will do the useless cumulative compaction after restart
weihongkai2008 opened a new issue #5556:
URL: https://github.com/apache/incubator-doris/issues/5556
When doris rewrites the t-1 day data every day, many tablete versions become [0-1],[2-2]. And these data will not be changed in the future. Under the current cumulative compaction logic, after doris be restarts, it will re-execute the compaction of the rowset of version [2-2]. At the same time, the number of such tablets is very large, resulting in a long query delay after be restarted. long. These compactions are not necessary because they have been done before the restart of dorie be.
