------------------------------------
Summary: Skip iterating through vertices in supersteps with just
global logic
Key: GIRAPH-1165
URL: https://issues.apache.org/jira/browse/GIRAPH-1165
Project: Giraph
Issue Type: Improvement
Reporter: Maja Kabiljo
Assignee: Maja Kabiljo
Priority: Minor
Some supersteps don't do anything with vertices but just do global worker or
master computation or perform aggregation. Not iterating through vertices in
these cases can save time (some time is still spent in zookeeper barrier but
that can be addressed separately).
