> Chukwa is running data aggregation in database, and it has the ability to
> generate SQL statements base on macros. On the other hand, there is also
> Consolidator program which Chukwa uses to down sample data in the database.
> Consolidator program can be replaced with the generic Aggregator program plus
> some macros. This enhancement will make the database aggregation framework
> cleaner.
