The method includes obtaining a snapshot of a source data node and recording incremental data in a to-be-migrated data shard in the source data node according to inventory data. The method includes migrating the inventory data to a target data node. The method also includes migrating the incremental data, and during the migration when the unmigrated incremental data satisfies a preset write-lock condition, instructing the source data node to perform a write-lock operation on the to-be-migrated data shard and migrate unmigrated incremental data to the target data node. The method further includes, after the migration of the incremental data is completed, instructing a coordinator node to switch a route corresponding to the to-be-migrated data shard from the source data node to the target data node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method, apparatus, and storage medium for migrating data node in database cluster","description":"The present disclosure is related to a method and an apparatus for data migration in a database cluster.
