                 @wankai123 Considering https://github.com/apache/skywalking/issues/12442, let's add a database version number concept in OAP codebase. Once we have this in place, we have a chance to do incompatible upgrade through two group.
   
   e.g. banyandb_db_schema_v = 1, and we need some incompatible upgrade, introduced a new kind of index, but the query logic is consistent. We could do banyandb_db_schema_v=2(compatible with banyandb_db_schema_v=1).
   
   Then, when we apply definition change through create new schema_v suffix groups.

   The DB(BanyanDB) server supported adding and deleting existing columns if there is no logic breaking.
   No need to use multiple groups to adopt this scenario.
   
   This will be required only when different versions of the file encoding system and indexing mode are accepted and supported by DB.
   
   I am closing this for now. We don't need to implement this in 10.3. Maybe later in DB 0.10 or 0.11, we will consider this in a more proper way when the use case is ready.
