Zusammenfassung:A data synchronization method and device for databases, and a storage medium are disclosed. The method includes: in the case where transaction response results fed back by multiple data nodes are all successful, receiving (S109) transaction commit request messages sent by a client, and writing (S110) a global transaction ID into a transaction processing list; sending (S111) the transaction commit request messages to the multiple data nodes; receiving (S112) transaction commit results fed back by the multiple data nodes; and in the case where the transaction commit results fed back by the multiple data nodes are all successful, applying (S114) to a global transaction manager to release the global transaction ID.
