URL: https://github.com/apache/doris/pull/16469
In vertical base compaction, same rows will be filtered in
verticam_merge_iterator, we should skip these filtered rows when set agg flag
of delete sign. For example, schema is a,b,delete_sign, and data is 1,1,1
1,1,0
1,1,0
2,2,1
2,2
and Block we get in VerticalBlockReader is
1,1,1
2,2,1
and we should set agg flag idex 0,4 to true when handle delete sign, so we
add a function continuous_agg_count to skip same rows filtered in
VerticalMergeIterator.
