]

Jihong MA updated CARBONDATA-437:
---------------------------------
    Description: row assembly speed is slow compared to other columnar file format after file
scan.  (was: we compared the record assembly from memory when we already load data from hdfs.
For parquet, it takes 43 ms for 100000 records, meanwhile carbon takes 86 ms for 100000 records
)
