Flink CDC的工作原理类似于Canal和其他类似的产品，它会连接到MySQL服务器作为复制 slave（模拟slave)，监听binlog日志，从而捕获数据库的变化。它可以伪装成一个slave节点去请求主节点的日志，在这个过程种，它可以通过请求master节点的二进制日志来获得数据更改。由于...

Flink CDC如何获得增量binlog,可能是跟canal一样,伪装成从节点获取日志?

Flink CDC捕获增量部分是单并行度读取mysql增量的binlog,至于如何获得增量binlog,可能是跟canal一样,伪装成从节点获取日志? 反正数据库有一条数据变化,都是可以捕获到的？

在Flink CDC中，本地模式（Local Mode）是指Flink任务在单个节点上运行

在Flink CDC中，本地模式（Local Mode）是指Flink任务在单个节点上运行，不启用任务并行度，所有算子都在一个线程中执行。在这种模式下，Flink CDC可以实现断点续传。具体来说，你可以通过以下步骤来实现断点续传：在全量同步开始前，记录同步位置。这可...

请教下大家Flink CDC，flink消费kafka中的数据，也配成3个节点的不是？

请教下大家Flink CDC，flink消费kafka中的数据，3个节点的kafka集群，kafka同时要接收来自mogodb的json格式的数据，这个时候kafka的这个参数advertised.listeners=PLAINTEXT://hdp12：9092也配成3个节点的不是

Flink CDC进行数据全量同步时，一直卡在第二个节点上，可以去调整什么参数？
