Description

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.
