架构</h2><p>TiCDC 作为 TiDB 的增量数据同步工具，通过 PD 内部的 etcd 实现高可用，通过多个 TiCDC 进程获取 TiKV 节点上的数据改变，在内部进行排序、合并等处理之后，通过多个同步任务 (Changefeed)，同时向多个下游系统进行数据同步。</p><p><img src="https://download.pingcap.com/images/docs-cn/ticdc/cdc-architecture.png" alt="TiCDC architecture"/></p><p>在以上架构图中：</p><ul><li>TiKV Server：代表 TiDB 集群中的 TiKV 节点，当数据发生改变时 TiKV 节点会主动将发生的数据改变以变更日志（KV change logs，简称 change logs）的方式发送给 TiCDC 节点。当然，当 TiCDC 节点发现收到的 change logs 并不是连续的，也会主动发起请求，获得需要的 change logs。</li><li>TiCDC：代表运行了运行 TiCDC 进程的各个节点。每个节点都运行一个 TiCDC 进程，每个进程会从 TiKV 节点中拉取一个或者多个表中的数据改变，并通过 Sink 模块同步到下游系统。</li><li>PD：代表 TiDB 集群中的调度模块，负责集群数据的事实调度，这个模块通常是由 3 个 PD 节点构成的，内部通过 etcd 集群来实现选举等高可用相关的能力。 TiCDC 集群使用了 PD 集群内置的 etcd 集群来保存自己的元数据信息，例如：节点的状态信息，changefeed 配置信息等。</li></ul><p>另外，从上面的架构图中也可以看到，目前 TiCDC 支持将数据同步到 TiDB、MySQL 数据库、Kafka 以及存储服务等。</p><h2 id="最佳实践" style="position:relative"><a href="#%E6%9C%80%E4%BD%B3%E5%AE%9E%E8%B7%B5" aria-label="最佳实践
