Ari Rabkin commented on CHUKWA-87:
----------------------------------

This is definitely a good idea.  Should we do CHUKWA-25 at the same time?

> There's a dependency between Hourly and Daily rolling. 
> This should be simplified to only be a generic compacter.  
> The compacter should run whenever there's more than xx spills files in the stream directory
and this could happen any time during the day.
> This may implies flattering the stream hierarchy but the logic for that is only on the
2 rolling classes and the MoveToRepo class.
> The compacter should be able to get the list of files, compact them, put the new file
in place and removed the one that have been part of the compacter M/R job.
> The compacter will be a daemon process that will always run in background.
