Xingjun Hao created CARBONDATA-3682:
---------------------------------------

             Summary: Support compress offheap data directly in the columnpage if the dataype is primitive
                 Key: CARBONDATA-3682
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-3682
             Project: CarbonData
          Issue Type: Sub-task
            Reporter: Xingjun Hao


If the datatype is primitve, like BOOLEAN/BYTE/SHORT/SHORT_INT/INT/LONG/FLOAT/DOUBLE/Decimal, the columnpage should be compressed based on the direct bytebuffer on the offheap directly, To avoid a copy from offheap to heap to reduce the GC overhead
