@kumarvishal09 ...I agree with you that we need these changes in
DictionaryBasedResultCollector also to improve the query performance when
number of columns are greater than 100.
As this PR is specifically for compaction performance fix, I will raise a
separate PR for this. I have raised a sub jira task under same jira to track
the issue.
