Abstract
A computer-implemented method for distributed graph database replica expansion and performed by a second data storage data node to be expanded includes, in response to reception of graph data migration information, entering a data copy-only mode and initiating graph data migration from a first data storage node to obtain a data snapshot of a first graph data shard. Following graph data migration, entering a data storage service mode and sending a graph data shard deletion notification to the first data storage node to delete the first graph data shard. In the data storage service mode, performing data synchronization with a corresponding first graph data shard of a primary replica based on a data point in the data snapshot. The first data storage node deletes a migrated graph data shard in response to the graph data shard deletion notification.
