------------------------------------

             Summary: Expand Mob Compaction Partition policy from daily to weekly, monthly
and beyond
                 Key: HBASE-16981
                 URL: https://issues.apache.org/jira/browse/HBASE-16981
             Project: HBase
          Issue Type: New Feature
          Components: mob
    Affects Versions: 2.0.0
            Reporter: huaxiang sun
            Assignee: huaxiang sun


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.
