---------------------------------------
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.
