What is Data Transfer Service?
Data transfer service (DTS) provides database data transfer service integrated with data migration, data synchronization and data subscription features, helping you achieve database migration without downtime and also use a real-time synchronization channel to easily build a highly available database architecture which allows remote disaster recovery.
DTS is designed to take over complicated data interaction activities, allowing you to focus on business development of the upper level.
- Data Migration
Database migration is available for different database types under different environments. Source databases that are supported for migration include self-built databases in a public network with public IP, self-built databases with access to Tencent Cloud via VPN, direct connection or other network environments, and self-built databases in CVM. The CDB instance is the destination database. You can check the statuses of all migration tasks and carry out multi-task batch operation.
The data migration feature offered by DTS is the best choice for migrating data onto cloud. Data migration only requires several steps of configuration to help you complete complicated activities for migrating your local data onto the cloud. The migration process does not prevent your source database from providing external service, thereby minimizing the effect on your business caused by the cloud migration task.
- Data Synchronization
The data synchronization feature offered by DTS implements real-time data synchronization between two CDB instances and is applicable to scenarios such as remote disaster recovery. Currently, data synchronization is only supported for CDB for MySQL instances.
- Data Subscription
DTS allows you to acquire real-time incremental update data of a cloud database and also to freely consume incremental data according to your business needs to achieve various business scenarios, such as implementation of cache update policy, async businesses decoupling, real-time synchronization of heterogeneous data sources and real-time synchronization of data containing complicated ETL. You may dynamically add or delete the subscription object, view subscription data online and modify the consumption time point.
