如果SQL Server Agent在开启了CDC或者复制之后被关闭,或者重启服务器之后SQL Server Agent没有随机自动启动 就有可能造成步骤2中的日志积压,也就是记录数据变化之后的事务日志处于replication状态,无法重用,导致没有可以使用的日志致使发生操作数据库的时候提示The transaction log for database '***' is full due to ...

If the scan.startup.mode parameter in the WITH clause for a MySQL CDC source table is set to initial, the connector for the MySQL CDC source table connects to the MySQL database by using a Java Database Connectivity (JDBC) driver, executes a SELECT statement to read full data, and then...
They also put undue pressure on operational databases, already under heavy load from applications, to deliver fresh data for analytics, resulting in database and application outages. What are the challenges when implementing change data capture? No single standard for CDC implementation methods ...
