> The snapshot file formats for SchemaRegion in Memory mode and Schema_File mode are incompatible with each other. If some nodes of the cluster are in Memory mode and some nodes are in Schema_File mode, errors may occur when loading snapshots.
> There are two kinds of solution:
>  # Add a DataNode registration check to ensure that the schema_engine_mode configuration of all DataNodes is consistent.
>  # Ensure compatibility when SchemaRegion loading snapshot, support for datanode heterogeneous configurations.
