Instead Of Whole CarbonRow
Key: CARBONDATA-3617
URL: https://issues.apache.org/jira/browse/CARBONDATA-3617
Project: CarbonData
Issue Type: Improvement
Components: data-load
Affects Versions: 1.6.1, 2.0.0
Reporter: Xingjun Hao
Fix For: 1.6.1, 2.0.0
During loading Data usesing globalsort, the sortby processing is based the
whole carbon row, the overhead of gc is huge when there are many columns.
Theoretically, the sortby processing can works well just based on the sort
columns, which will brings less time overhead and gc overhead.
