   **Describe the question**
   I am in the process of using DS, because the data rectification, I put some 
data deleted, but the original workflow still use the data source, so I need to 
each point to change the data source, the vast number of workflow, so I want to 
by direct changes to the source database data source in the form of a one-time 
change, but I found some problems.I'm looking at t_ ds_ task_ Instance, we 
found that all datasource IDs are stored in JSON, 
   
   **What are the current deficiencies and the benefits of improvement**
   which is obviously not conducive to batch change. Therefore, I wonder if 
datasource ID can be stored in a separate field. Of course, this is just my 
idea. I don't know what the developers are thinking.Please forgive me if I am 
wrong.
   
   **Which version of DolphinScheduler:**
    -[1.3.5-preview]
