Databases Supported by Data Sync

Last updated: 2021-11-16 18:07:40

DTS supports sync of self-built, TencentDB, and third-party cloud databases. Below are the specific network connection methods:

  • Public Network: the source database can be accessed through a public IP.
  • Self-Build on CVM: the source database is deployed in a CVM instance.
  • Direct Connect: the source database can be interconnected with VPCs through Direct Connect.
  • VPN Access: the source database can be interconnected with VPCs through VPN Connection.
  • VPC: the source and target databases are both deployed in Tencent Cloud VPCs. The data sync feature supports the VPC access type. To use it, submit a ticket for application.
  • Database: the source database is a TencentDB database.
  • CCN: the source database can be interconnected with VPCs through CCN.

For a third-party cloud database, you can select Public Network generally or select VPC Access, Direct Connect, or CCN based on your actual network conditions.
