Description
问题描述： 从MySQL复制到MySQL，配置为5个channel，如果突然网络中断（中断持续到数据库释放了链接），此时全量同步的程序终止；改用基于ID的增量复制补数据，然后得到的最大id不正确，最终导致数据不完整。
请问大佬们，这种问题有招么？

Research direction
Start by examining DataX's MySQL-to-MySQL path for five-channel concurrent synchronization and its handling of network interruption during full sync. Reproduce the failure where full sync stops, then compare the ID-based incremental recovery result with the source's maximum ID; done means recovery does not leave data incomplete.
