If changes in input row are not related to partition key, order key and window function arguments, the changes can be emitted to downstream directly.
For any rank-series and aggregate functions that supports incremental computation, jump to the first current key directly instead of sliding one by one.
For dense_rank, if a newly inserted row has same value with existing ones, then no other rows need to be updated.
