> Heterogeneous schema_engine_mode among DataNodes
> ------------------------------------------------
>
> Key: IOTDB-5545
> URL: https://issues.apache.org/jira/browse/IOTDB-5545
> Project: Apache IoTDB
> Issue Type: Improvement
> Reporter: yanze chen
> Assignee: Yukun Zhou
> Priority: Major
>
>
> 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.
