> Key: CARBONDATA-888
> URL: https://issues.apache.org/jira/browse/CARBONDATA-888
> Project: CarbonData
> Issue Type: Improvement
> Components: spark-integration
> Affects Versions: 1.2.0-incubating
> Environment: HDP 2.5, Spark 1.6
> Reporter: Sanoj MG
> Priority: Minor
> Fix For: 1.2.0-incubating

> While creating a Carbondata table from dataframe, currently it is not
> possible to specify columns that needs to be included in or excluded from the
> dictionary. An option is required to specify it as below :
> df.write.format("carbondata")
> .option("tableName", "test")
> .option("compress","true")
> .option("dictionary_include","incol1,intcol2")
> .option("dictionary_exclude","stringcol1,stringcol2")
> .mode(SaveMode.Overwrite)
> .save()
> We have lot of integer columns that are dimensions, dataframe.save is used to
> quickly create tables instead of writing ddls, and it would be nice to have
> this feature to execute POCs.
