huaxiang sun commented on HBASE-16981:
--------------------------------------
Following jingcheng's suggestion, it is like after the threshold for the number
of the files, the mob compactor chore is going to perform a major mob
compaction based on current policy. My initial thinking is that the chore is
going to do minor mob compaction as it does today based on the policy. And the
users will do a manual major mob compaction so they have more control. If we
agree on Jingcheng's suggestion, I can start to implement it. Thanks
> Expand Mob Compaction Partition policy from daily to weekly, monthly and

> 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.
