----------------------------------------

             Summary: optimize double/float stats collector
                 Key: CARBONDATA-3753
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-3753
             Project: CarbonData
          Issue Type: Improvement
            Reporter: Ajantha Bhat
            Assignee: Ajantha Bhat


Problem:

For every double/float column's every value. we call 

*PrimitivePageStatsCollector.getDecimalCount(double value)*

problem is, here we create new bigdecimal object and  plain string object every time.

Which leads in huge memory usage during insert

 

Solution:

Create only Bigdecimal object and use scale from that.
