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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
