> Key: HBASE-25302
> URL: https://issues.apache.org/jira/browse/HBASE-25302
> Project: HBase
> Issue Type: Improvement
> Reporter: Xiaolin Ha
> Assignee: Xiaolin Ha
> Priority: Major
>
> We have implemented a fast continuous split region method using HFileLink,
> depending on the stripe store file manager.
> It is very simple and efficiency, we have implement all the ideas described
> in the design doc and used on our production clusters. A region of about 600G
> can be splitted to 75G*8 regions in about five minutes, with less than 5G
> total rewrite size(all are L0) in the whole process, while normal continuous
> split needs 600G*3=1800G. If using movement for same table HFileLinks, the
> rewritten size is less than 50G(two stripe size), because the rebuild of
> HFileLinks to stripes may insert some files to L0.
> Details are in the doc,

> If there is someone who has interest in this issue, please let me know,
> thanks.
