TiCDC Deployment Topology

Note:

TiCDC is a feature for general availability (GA) since v4.0.6. You can use it in the production environment.

This document describes the deployment topology of TiCDC based on the minimal cluster topology.

TiCDC is a tool for replicating the incremental data of TiDB, introduced in TiDB 4.0. It supports multiple downstream platforms, such as TiDB, MySQL, and MQ. Compared with TiDB Binlog, TiCDC has lower latency and native high availability.

Topology templates

Note:

  • You do not need to manually create the tidb user in the configuration file. The TiUP cluster component automatically creates the tidb user on the target machines. You can customize the user, or keep the user consistent with the control machine.
  • If you configure the deployment directory as a relative path, the cluster will be deployed in the home directory of the user.
