GEODE-2587: Refactored the OrderByComparator's compare method
----
> Refactor OrderByComparator's compare method
> -------------------------------------------
>
> Key: GEODE-2587
> URL: https://issues.apache.org/jira/browse/GEODE-2587
> Project: Geode
> Issue Type: Bug
> Components: querying
> Reporter: nabarun
>
> OrderByComparator's compare method creates a lot of objects / arrays with the
> intention of comparing two objects.
> But allocation of memory for these objects results in GC to kick in.
> The additional time consumed in GC results in increased execution time for
> queries with ORDER BY clause.
> This method must be refactored to require less memory allocations in order to
> compare and thus speed up ORDER BY clause.
