             Summary: Add benchmark for Change Data Capture scenario
                 Key: CARBONDATA-3244
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-3244
             Project: CarbonData
          Issue Type: Improvement
            Reporter: Jacky Li


CDC (change data capture) is a common scenario for analyzing slowly changed table in data warehouse.
It is good to add benchmark test comparing two update methods:
1. hive_solution, which uses INSERT OVERWRITE. This is a popular method for hive warehouse.
2. carbon_solution, which uses CarbonData's update syntax to update the history table directly.
