URL: https://github.com/apache/doris/pull/13690
This feature mainly handle compaction for ordered data, adding a min_max key
for segment and check if rowset are non-overlapping so we can do compaction
just move files and modify rowset meta instead of traverse all rows.
The strategy list below:
1. more than half of rowsets are non overlapping.
2. all segments are more than 10M
3. if base compaction, no delete version contains in input_rowsets.
By the way, my test shows that calc min max key does not effect load
performance.
