> After entering the Stream phase, the offset consumed by the global slot is 
> committed upon the completion of each checkpoint, preventing log files from 
> being unable to be recycled continuously, which could lead to insufficient 
> disk space.
> However, the job can only restart from the latest checkpoint or savepoint. if 
> restored from an earlier state, WAL may already have been recycled.
>  
> The way to solve it is to commit the offset after every multiple checkpoint 
> cycles. The number of checkpoint cycles is determine by connector option, and 
> the default value is 3.
