Can someone please EXPLAIN the difference between BASE and CUMULATIVE at <https://docs.starrocks.io/docs/3.5/sql-reference/sql-statements/table_bucket_part_index/ALTER_TABLE/#manual-compaction-from-31>
The actual usage of the same word is duplicated but not actually defined.

```BASE COMPACT ```
is used on older data, merging it into one big base data.
```CUMULATIVE COMPACT```
is used on newer data, typically smaller in size.

Thanks for answer. I think it should be in documentation to not need search questions.
