不好意思，我也没有解决 😂 。集群里面去配置 connection.pool.size 确实是不生效的 |

好像是伪装从库多了不行，所以datastream多表比较好，群里也见别人遇到这问题，不知道有没有解决 |

你说的 datastream 是指用 Flink datastream api 方式处理？ |

本地部署了 2个 taskManger 节点，1个 jobManager节点 其中 1个taskManager与JobManager部署在同一台服务器上。
我使用CDC进行作业，前面20个作业正常运行。但到了 21 个任务创建时出现了连接超时异常。
我查看了官方文档，但依然不确定需要修改什么配置。为什么CDC任务只能创建20个呢？
我确认了我的mysql数据库可用连接数充足，并且taskManger的资源充足。
