csun5285 opened a new pull request, #61100:
URL: https://github.com/apache/doris/pull/61100
### 1. `vertical_compaction_num_columns_per_group`
- Allow modifying this table property via `ALTER TABLE SET(...)`. This
controls how
many columns are merged in each group during vertical compaction. For wide
variant
tables, reducing this value significantly reduces peak
memory usage during compaction.
### 2. `variant_doc_materialization_min_rows`
- Remove the restriction that prevented modifying this variant column
property via
`ALTER TABLE MODIFY COLUMN`. This property controls the minimum row
threshold for
materializing variant sub-columns. The change is propagated via Light Schema
Change.
