- Unique Key table and Primary Key table

StarRocks replaces each newly loaded record with the previously loaded record and retains only the most recently loaded record as a row in the table. After the loading is complete, the table does not contain rows that have the same primary key. The Unique Key table and the Primary Key table can be considered a special Aggregate table in which the REPLACE aggregate function is specified for metric columns to return the most recent record among a group of records that have the same primary key.
