Hi

In Spark-shell, you can use the below script :

import org.apache.carbondata.core.util.CarbonProperties
import org.apache.carbondata.core.constants.CarbonCommonConstants

CarbonProperties.getInstance().addProperty(CarbonCommonConstants.ENABLE_VECTOR_READER, "true")
CarbonProperties.getInstance().addProperty(CarbonCommonConstants.ENABLE_OFFHEAP_SORT, "true")
CarbonProperties.getInstance().addProperty(CarbonCommonConstants.ENABLE_UNSAFE_SORT, "true")

Hi,
   Datasize 1024MB(Default).I load data into Carbon Table through Spark-Shell. The presto plugin of Carbon supports the "carbondata-store" property only.How do I add the properties you listed?
