---------------------------------

             Summary: DataNode registration check for schema_engine_mode
                 Key: IOTDB-5545
                 URL: https://issues.apache.org/jira/browse/IOTDB-5545
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: yanze chen
            Assignee: yanze chen


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. Therefore, it is necessary to add a DataNode registration check to ensure that the schema_engine_mode configuration of all DataNodes is consistent.
