> Currently Falcon has dependency APIs which lists the entity dependencies.
> i.e. A dependency of a process lists all the input and output feeds and corresponding clusters.
> With the new process DAG API, it should generate .DOT file which can be easily converted to visual graph.
> All the processes are linked by the configured feeds.
> EX: If process A generates feeds 1,2 and feed 1 is consumed by process B and 2 by process C respectively, then the .DOT file should generate adjacency matrix.
> Graph start{
> A -> B
> A -> C
> ..
> ..
> B->D
> D->E
> }
> Unless we build dashboard this API will be handy for users.
