----------------------------------------
Summary: Reduce Memory footprint and store size for local
dictionary encoded columns
Key: CARBONDATA-2760
URL: https://issues.apache.org/jira/browse/CARBONDATA-2760
Project: CarbonData
Issue Type: Improvement
Reporter: kumar vishal
Assignee: kumar vishal
*Problem*
# Local dictionary encoded page is using unsafevarlenghtcolumn column page
which internally maintains offset of each value in another column page because
of this memory footprint is high.
# for complex primitive string data type column page while compressing, it is
converting to LV even if it is encoded with dictionary values, because of this
store size is high.
*Solution:*
# Use UnsafeFixedLength Column page for local dictionary encoded columns
# No need to convert to LV during query if local dictionary is present so use
UnsafeFixLength Column page
