   I plan to implement data lineage function (Table level).
   
   - The sql node and etl node automatically parse the dependency table and 
target table.
   - The frontend controls whether to enable dependency detection through 
switch.
   - The master server automatically injects dependent nodes, create dependent 
nodes based on dependencies.
   - Rely on the node to set the default number of retries.
   - Open the node that dependent detection function, no longer need to 
manually connect.
   
   Already start a discussion in mail list.
