Node Connectivity
There are 33 nodes that can be used as predessesor
for a node with an input port of type 
org.uni_leipzig.biggr.ports.FlinkPortObject.
DOT DataSink
Writes Gradoop Graphs as Graphviz DOT into a file.
Graph Clustering For Viewer
Computes a 2 level hierarchical clustering of a logical graph which can be explored with the Big Graph Viewer.
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.
HITS
Hyperlink-Induced Topic Search computes two interdependent scores for every vertex in a directed graph.
Label Propagation
Label Propagation algorithm to detect communities in a logical graph.
