Hello all :)

I am programming an application that has to create and destroy a few vertices. I was wondering if there is any protection in Giraph to prevent a vertex to send a message to another vertex that does not exist (i.e. provide a vertex id that is not associated with a vertex yet).

Is there a way to test if the destination vertex exists before sending the message to it?

Also, when a vertex is created, is there any source of load balancing or it is always kept in the worker that created it?

Best Regards,
