Hi Ufuoma, Gelly doesn't support dynamic streaming graphs yet. The project Andra has linked to is a prototype for *one-pass* streaming graph analytics, i.e. no graph state is maintained.
If you would like to keep and maintain the graph state in your streaming program, you would have to implement it yourself. Take a look at the relevant section of the programming guide [1] and please let us know if you have questions! Cheers, -Vasia.
