Overview

Data Transfer Service (DTS) supports multiple types of databases, such as MySQL, MariaDB, Percona, TDSQL-C, TDSQL for MySQL, PostgreSQL, Redis, MongoDB, and SQL Server. It helps you migrate your databases to the cloud without interrupting your business and build a high-availability database disaster recovery architecture through real-time sync channels. It provides the data subscription feature to meet your requirements for commercial data mining and async business decoupling.
DTS also provides a special edition: DTS-DBbridge‌, which can be independently deployed on the private cloud. DTS-DBbridge‌ supports data migration and sync between heterogeneous and homogeneous databases, enabling you to migrate an entire database, such as an Oracle database.

Product Features

Data migration Data migration refers to the process of replicating data between different data sources. DTS supports non-stop data migration to minimize the impact of database downtime on the business. This feature can be used to migrate data from local databases, TencentDB databases, and third-party cloud databases to TencentDB.

Data sync Data sync refers to the process of syncing data between two database sources in real time. It is suitable for cloud-local active-active, multi-site active-active, and cross-border data sync as well as real-time data warehousing.
While data migration involves moving the entire database in one go, data sync is an ongoing process that will keep the data synced between the source and target databases to ensure consistency.

Data subscription Data subscription refers to the process where DTS gets the data change information of a key business in the database, converts it into message objects, and pushes them to Kafka for the downstream businesses to subscribe to, obtain, and consume. DTS allows you to directly consume data through a Kafka client, so that you can implement data sync between TencentDB databases and heterogeneous systems, such as cache update, real-time ETL (a data warehousing technology) sync, and async business decoupling.
