[jira] [Created] (GEODE-7150) Use LONG instead of INT in Aggregation Functions

Juan José Ramos Cassella created GEODE-7150:
-----------------------------------------------

             Summary: Use LONG instead of INT in Aggregation Functions
                 Key: GEODE-7150
                 URL: https://issues.apache.org/jira/browse/GEODE-7150
             Project: Geode
          Issue Type: Bug
            Reporter: Juan José Ramos Cassella


OQL aggregate functions ({{COUNT}} and {{AVG}}) can “silently” overflow as Geode internally uses {{int}} to compute the aggregations, basically meaning that we can return an overflowed value instead of the proper result.
As an example, if {{COUNT}} evaluates to {{2147483648 (Integer.MAX_VALUE + 1)}} the user will receive {{-2147483648 (Integer.MIN_VALUE)}} and so on.
We should modify the internal implementation to use `Long` instead of `Int`, and properly document the limitation (see GEODE-7146).
