Xiaolin Ha created HBASE-25302:
----------------------------------

             Summary: Fast continuous split regions
                 Key: HBASE-25302
                 URL: https://issues.apache.org/jira/browse/HBASE-25302
             Project: HBase
          Issue Type: Improvement
         Environment: We have implemented a fast continuous split region method using HFileLink, depending on stripe store file manager.

It is very simple and efficiency, we have implement all the ideas 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 50G total rewrite size in the whole process, while normal continuous split needs 600G*3=1800G.

Details are in the doc,
