> Today the mob region holds all mob files for all regions. With daily 
> partition mob compaction policy, after major mob compaction, there is still 
> one file per region daily. Given there is 365 days in one year, at least 365 
> files per region. Since HDFS has limitation for number of files under one 
> folder, this is not going to scale if there are lots of regions. To reduce 
> mob file number,  we want to introduce other partition policies such as 
> weekly, monthly to compact mob files within one week or month into one file. 
> This jira is create to track this effort.
