https://github.com/apache/carbondata/pull/1381 [CARBONDATA-1449]Fixed date and timestamp filter gc issue in case of direct dictionary
**Problem:** When date or timestamp filter is going to row level there is lots of gc this is because for each row it is creating new direct dictionary object for data type;
**Solution:** create one object and use the same.
Improvement tested with 2million rows:
~19 seconds to ~9 seconds
