> Currently, the SchemaRegionSchemaFileImpl relies on mlog and schema file to recover. 
> In cluster mode, schemaRegion relies on Ratis to guarantee consistency, while raftlog takes repeating info of mlog. 
> We want to use raftlog to recover info not in snapshot and use schema file to implement snapshot and online business.
