>            Priority: Critical
> *Requirement*-: Need to Run Template With Same Logics on Different Tables 
> Data.(Example is Given Below)
> *Need*: Default Coder is Required So According to Data It Make All Fields as 
> String and Read Data else Thier must be Dynamic Options to Read Coder From 
> GCS as JSON FILE and Parse Data on Basis of That (But We can Pass Location 
> Using ValueProvider) or SomeWhere Else so At Runtime Using ValueProvider.
> *Examples*: I Have Two Tables 1 is Having Column (NAME, CLASS, ROLL, 
> And 2 Table is (NAME, ROLL, SUB, TEST_MARKS)
> On Both Tables, I am Just Sorting Table on Basis Of Roll Number so if We can 
> Read Coder at Run Time The Same Template Can Be Used For Different Tables at 
> Run Time.
