------------------------------------
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.
