Hello @Seenuvasan, Venkatanathan !
Yes the default order starts from 0
The sink with the lowest order value executes first, followed by sinks with higher order values. The default order value for a sink is 0 if it is not explicitly set.
No you cannot make modifications , you have to recreate the dataflow in each case , thats why you cannot make changes in the order.
I hope this helps!
