Review Comment:
   Just a personal question, might be missing something here — since flussConf 
is a member field of the source, calling set seems to mutate it in place, and 
this config eventually gets passed down to the Connection and shared by the 
downstream scanners. So I'm wondering whether multiple readers reusing the same 
instance could end up sharing the same config. Would it be safer to copy it 
first before setting?
   Curious how you see it @luoyuxia ?
