Graphulo provides the ability to run breadth-first searches once a graph is loaded.
###Required Parameters
These parameters must be included as input parameters in order to execute a breadth-first search.
- AccConfigFile: Name of file containing Accumulo configuration information
- GraphTable: Name of Accumulo table containing the graph to be searched.
- v0: Starting nodes, like "a,f,b,c,". Null or empty string "" means start from all nodes. v0 may be a range of nodes like "c,:,e,g,k,:,".
- k: Number of steps
- ResultTable: Name of table to store result. Null means don't store the result.
- BFSConfigFile: Name of file containing additional BFS configuration information.
###Configuration File
These are optional parameters to the algorithm and provide additional options that might be useful for an application's needs.
- minDegree: (not implemented) Minimum out-degree. Checked before doing any searching, at every step, from ADegtable. Pass 0 for no filtering.
- maxDegree: (not implemented) Maximum out-degree. Checked before doing any searching, at every step, from ADegtable. Pass Integer.MAX_VALUE for no filtering.
- newVisibility: (not implemented) Visibility label for new entries created in Rtable and/or RTtable. Null means use the visibility of the parent keys. Important: this is one option for which null (don't change the visibiltity) is distinguished from the empty string (set the visibility of all Keys seen to the empty visibility).
- useNewTimestamp: (not implemented) If true, new Keys written to Rtable/RTtable receive a new timestamp from {@link System#currentTimeMillis()}. If false, retains the original timestamps of the Keys in Etable.
