zhuqi created HBASE-25244:
-----------------------------

             Summary: Support splitting a region into N parts at a time
                 Key: HBASE-25244
                 URL: https://issues.apache.org/jira/browse/HBASE-25244
             Project: HBase
          Issue Type: New Feature
          Components: regionserver
            Reporter: zhuqi
            Assignee: zhuqi


In the current reference file format, only one parent region split into two references can be recorded. At this time, if you want to continue splitting the daughter region, you must wait until the majorCompaction is over and the reference file is deleted before you can continue to split the region.

If the reference file can point to other refenrence files, that is, the data has not been moved from the parentRegion to the region under the corresponding folder, thereby establishing a multi-level reference. At this time, a tree structure is formed. Only the root contains physical data, and the region on the leaf node region is serving.
