在启动模式为initial(默认值)时,MySQL CDC源表会先通过JDBC连接MySQL,使用SELECT语句读取全量的数据,并记录Binlog的位点。全量阶段结束后,再从记录的位点开始读取Binlog中的增量数据。 全量阶段时,由于通过SELECT语句查询数据,MySQL服务的查询压力可能会增加。增量阶段时,需要通过Binlog Client连接MySQL读取Binlog,当使用...
解法《二》或者修改mysql文件下的 [mysqld]和[mysql]添加 sql_mode ='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'; 1. 场景(二)使用django出现这个问题 ...
