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