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/Flink 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.
Subscribed data in Protobuf, Avro, or JSON formats can be consumed. ProtoBuf and Avro adopt the binary format with higher consumption efficiency, while JSON adopts the easier-to-use lightweight text format.
DTS supports data subscription for the following types of databases.
