>                 URL: https://issues.apache.org/jira/browse/CARBONDATA-4025
>             Project: CarbonData
>          Issue Type: Improvement
>          Components: core
>    Affects Versions: 2.0.1
>         Environment: Apcahe carbondata 2.0.1
> Apache spark 2.4.5
> Hadoop 2.7.2
>            Reporter: suyash yadav
>            Priority: Major
> We are doing a POC based on carbondata but we have observed that when we 
> create n MV on a table with timeseries function of same granualarity the MV 
> takes double the space of the table.
> In my scenario, My table has 1.3 million records and MV also has same number 
> of records but the size of the table is 3.6 MB but the size of the MV is 
> around 6.5 MB.
> This is really important for us as critical business decision are getting 
> affected due to this behaviour.
