Data Transmission Service:Create consumer groups

Prerequisites

A change tracking instance is created and its status is Normal. For more information, see Overview of change tracking scenarios.

Usage notes

• If the size of a single row of data that you track exceeds 16 MB, an out of memory (OOM) error may occur on the change tracking client.

• You can create a maximum of 20 consumer groups in a change tracking instance to achieve repeated data consumption.

• You can create only a single consumer in each consumer group.

• DTS reads incremental data by using the DStore module or a client. If you switch the module or client, data duplication may occur.
