…ud mode (apache#37557) 1. In cloud mode the updated rowset meta after `rowset->merge_rowset_meta` in `BaseTablet::update_delete_bitmap` will be lost in `update_tmp_rowset`.So in order to keep the latest schema we should keep schema in update_tmp_rowset 2. cloud tablet should also do copy_without_variant_extracted_columns
…t column (apache#37674) …t column Eg. segment 1 has no variant columns and fill the dst with default value, which the variant columns's root is type nothing with n rows(not finalized), then reading segment2 with the none finalized variant column will lead to nullptr in `obj.get_root();`
…he#37839) `finalize` may change the inner data structure in ColumnObject, and lead to heap use after free in some scenario ## Proposed changes Issue Number: close #xxx <!--Describe your changes.-->
