Hi @vasia,
thanks for your comments! I thought about this extension in a different
way. Whenever you have a graph that is too big to process it with delta
iteration you could just turn on bulk mode to get the computation done. It will
be a lot slower, but sometimes this might be better then not getting any
results.
I dont think a dedicated bulk operator would be very useful. People can
just use plain Flink if they dont need the Pregel abstraction. And in most
cases it would be much slower then using the current solution.
You know gelly and its usecases a lot better then me. If you dont think
that a mode like this might be userful I am totally find with that. It is a
very small change anyway.

> Reporter: Markus Holzemer

> Priority: Minor

> For my research I need to execute graph algorithm with delta iterations and
> with bulk iterations. So I added an execution mode to gelly that executes the
> vertex centric iteration with a bulk iteration.
> Since gelly normally keeps the whole graph in the solution set of the delta
> iteration, it can only handle graphs that fit into the distributed memory of
> ones nodes (correct me if I am wrong). So a bulk mode could also be usefull
> for handling graphs that do not fit in memory.
