morningman opened a new pull request #8072:
URL: https://github.com/apache/incubator-doris/pull/8072
# Proposed changes
Issue Number: close #8058
## Problem Summary:
1. Fix the problem of BE crash caused by destruct sequence. (close #8058)
2. Add a new BE config `compaction_task_num_per_fast_disk`
This config specify the max concurrent compaction task num on fast
disk(typically .SSD).
So that for high speed disk, we can execute more compaction task at same
time,
to compact the data as soon as possible
3. Avoid frequent selection of unqualified tablet to perform compaction.
4. Modify some log level to reduce the log size of BE.
