> ---------------------------------------------------------------------------------------

> Key: CARBONDATA-863
> URL:
https://issues.apache.org/jira/browse/CARBONDATA-863> Project: CarbonData
> Issue Type: Improvement
> Reporter: Manish Gupta
> Assignee: Manish Gupta
> Priority: Minor
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Currently during alter add and drop columns operation, dictionary files for columns are being added and dropped in a single thread due to which the operation becomes very slow as the number of columns increases.
> Instead this operation should be done through RDD which will make optimal use of executor cores configured and performance will increase by number of cores configured.
