Jeff,
Thanks a lot for you answer. However, I am still not able to completely
understand how it is going, simply looking at
routeDataMovementEventToDestination methods
in:BroadcastEdgeManagerOneToOneEdgeManagerScatterGatherEdgeManager
So for broadcast, I guess every input task has a connection with every output
task. One to One, means every input task has a connection with only one output
task, on the assumption they are equal or less than number of output tasks.
What about scatter gather ?
Thanks,Robert

Hi Robert,
Please refer EdgeManagerPlugin, there's several implementations for
difference communication pattern (BroadcastEdgeManager, OneToOneEdgeManager,
ScatterGatherEdgeManager). Which one is used depend on what DataMovementType
you specify when you connect vertices.

Hi guys,
I want to better understand how the input / output data circulates across tasks
from different vertices. Specifically I am wondering what are the communication
patterns across tasks in different vertices.(many to many, many to one, one to
many ...).
Can someone explains me how I can identify this for every pair of parent /
children vertices ? Is there some property per task which allows me to see
that, or do I need to look at types of vertices ?
Thanks,Robert
