It can connect MySQL and convert binlog to defined record. I think we can add 
the dependency of Debezium to solve the problem.

   I came up this idea because the current Canal design is running 
synchronization job on FE, and send data to BE. Or do you know some cpp lib 
that similar with Debezium?
