> 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.
