…n=true` (apache#48399) apache#39558 add a config to support shadow tablet to do cumulative compaction during schema change in cloud mode to avoid -235 error on new tablet in the case of a large number of loads. However, this introduces correctness problem on merge-on-write table because some rowsets' delete bitmaps are wrong if there are cumu compactions on new tablet when SC calculate delete bitmaps for incremental rowsets after converting historical data. This PR introduce a new type of compaction `STOP_TOKEN` to fail all existing compaction jobs and disallow doing any compaction on tablet and change the SC process as following: 1. converting historical data 2. register stop token on new tablet to fail all existing compaction jobs and disallow doing any compaction on new tablet 3. calculate delete bitmap for incremental rowsets without lock 4. calculate delete bitmap for incremental rowsets with lock 5. commit SC job and remove stop token ---- ref: apache#29386
