[Fix](partial-update) Correct the alignment process when the table has sequence column and add cases ( #25346 ) ...
This PR fix the alignment process during publish phase when conflict occurs during concurrent partial updates: if we encounter a row with the same key and larger value in sequence column, it means that there exists another load which introduces a row with the same keys and larger sequence column value published successfully after the commit phase of the current load. We should act as follows:
- If the columns we update include sequence column, we should delete the current row becase the partial update on the current row has been overwritten by the previous one with larger sequence column value.
- Otherwise, we should combine the values of the missing columns in the previous row and the values of the including columns in the current row into a new row.
