>                 Key: HBASE-24664
>                 URL: https://issues.apache.org/jira/browse/HBASE-24664
>             Project: HBase
>          Issue Type: Improvement
>          Components: regionserver
>    Affects Versions: 3.0.0-alpha-1, 2.4.0
>            Reporter: Zheng Wang
>            Assignee: Zheng Wang
>            Priority: Major

> As a distributed cluster, HBase distribute loads in unit of region, so if 
> region grows too big,
>  it will bring some negative effects, such as:
>  1. Harder to homogenize disk usage(consider locality)
>  2. Might cost more time on region opening
>  3. After split, the daughter region might lead to more io cost on compaction 
> in a short time(if write evenly)
> I tried to introduce a new SteppingAllStoresSizeSplitPolicy in HBASE-24530, 
> but after discussed in comments and related 
> [thread|https://lists.apache.org/thread.html/r08a8103e2532eb667a0fcb4efa8a4117b3f82e6251bc4bd0bc157c26%40%3Cdev.hbase.apache.org%3E],
>  finally we decide to change the existing split policy with a new option that 
> if it should count all store files, and for master it would be true, else 
> false.
