             Summary: optimize compress/decompress related procedure
                 Key: CARBONDATA-2944
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-2944
             Project: CarbonData
          Issue Type: Sub-task
            Reporter: xuchuanyin
            Assignee: xuchuanyin


While implementing customize compressor, I found that carbon compressor deal with primitive object while compressing/decompressing which I think will cause efficiency because:
1. many compressor do not provide compress/decompress interface for primitive objects, we need to handle it ourselves, which may cause unnecessary conversion from primitive to bytes and from bytes to primitives;
2. for querying, we need to decompress the content. I think it's better to keep them in bytes and convert them to primitives until it is needed.
