> - Giraph trunk
> - Titan 0.4.4

> *Problem:*
> https://giraph.apache.org/rexster.html
> When Giraph reads from Titan DB via Rexster, it uses api like below
> /graphs/%s/tp/giraph/%s/rexster.offset.start=%s&rexster.offset.end=%s
> - offset.start : index of start vertex
> - offset.end : index of end vertex
> Titan DB has 100 vertices and I want to read vertices 1 to 10.
> So, I set
> offset.start = 1
> offset.end = 10
> But, Rexster read whole vertices from Titan DB.
> *Reason:*
> giraph-rexster/giraph-kibble/src/main/java/org/apache/giraph/rexster/kibble/IteratorVertex.java
> There was a vertex count variable, but it didn't work correctly. (it didn't increase)
> *Solution:*
> Add code to increase vertex count
