Node Connectivity
There are 19 nodes that can be used as predessesor
for a node with an input port of type 
LogicalGraph.
Graphs -> Graph
Combines all graphs in a collection into one logical graph.
CSV DataSource
Loads graph data from a directory containing a logical graph or a graph collection in Gradoop CSV format.
Customizable CSV Reader
Load a graph from different vertex and edge csv files. The vertices and edges can be in an external representation.
EdgeList DataSource
Load graph data from a directory containing a file representing (labeled-)edge list.
Aggregates
Counts all nodes and edges in the logical graph and adds these counts as attributes to the graph head.
Combine
Creates the union/intersection/difference of two logical graphs.
Distinct Vertex Degrees
Calculates the vertex degree for each vertex of a logical graph: In-degree, out-degree and sum of both. Adds these informations as new properties to […]
Fusion
The general idea of this operator is that everything that appears in the pattern graph is fused into a single vertex into the search graph.
Graph Sampling
Takes a logical graph and picks a subset of vertices or edges from this graph.
Grouping
Groups vertices/edges by labels/properties and calculates aggregations on those groups.
