titan-tools is a set of tools for repairing inconsistencies in titan cassandra backed graph databases

titan-tools will:

• repair indicies that reference deleted vertices or associate incorrect values with existing vertices
• perform graph wide reindex for a type
• properly remove partially deleted vertices

• clone repo and build project
• copy titan-tools-*.jar into titan/lib
• start bin/gremlin.sh
• see below for gremlin shell usage

//first, create your graph instance
g = TitanGraphFactory.open('cassandra.properties')

//second, instantiate a TitanGraphTools object
fx = com.shift.titantools.TitanGraphTools.create(g)

//find problems, but don't repair
fx.checkType("type_name")

//find problems, and repair
fx.repairType("type_name")

//perform a graph wide reindex of a type
fx.reindexType("type_name")

//find, but don't delete partially deleted vertices
fx.checkVertices()

//find and delete partially deleted vertices
fx.cleanVertices()

Titan Tools is

• a new project
• has only been tested against Titan 0.2.1

so test your repairs on a local copy of your graph first!
