TiCDC Deployment Topology
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, Kafka, MQ, and storage services. Compared with TiDB Binlog (deprecated), TiCDC has lower latency and native high availability.
