> Improve data aggregation in database
> ------------------------------------
>
> Key: HADOOP-4827
> URL: https://issues.apache.org/jira/browse/HADOOP-4827
> Project: Hadoop Core
> Issue Type: Improvement
> Components: contrib/chukwa
> Environment: Redhat EL 5.1, Java 6
> Reporter: Eric Yang
> Assignee: Eric Yang
>
> 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.
