Summary: Support creation and deletion of dictionary files through RDD during alter add and drop 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 Fix For: 1.1.0-incubating 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
