How to create and start working with a graph database in Titan/Rexster from Bulbs

I've downloaded titan-server-0.4.4.zip and unzipped it and ran :

$ bin/titan.sh start

This started both Cassandra and Titan + Rexster. Now, I want to create a new graph for my application (say 'ggg') that I want to create from Bulbs in my Python source code. This is what I tried in the python2.7 console : 

>>> from bulbs.titan import Graph, Config
>>> config = Config('/home/kevin/ggg') 
>>> g = Graph(config)     # Hoping that this will create all the graph related files

Now, I went to the rexster web interface and I could see only one graph named graph

{"version":"2.4.0","name":"Rexster: A Graph Server","graphs":["graph"],
"queryTime":0.567623,"upTime":"0[d]:05[h]:43[m]:05[s]"}

Is there something that I am doing wrong or missing? I tried looking at the documentation but couldn't find anything that helped me with this.

Thanks for your time.

Solution

  • you need to edit rexster's config file to inform it about the new graph. this is my config/rexster.xml entry

    <graph-name>productionDB</graph-name>
  <graphtype>com.thinkaurelius.titan.tinkerpop.rexster.TitanGraphConfiguration</graphtype>
  <graph-location>/db/titan/main</graph-location>
  <graph-read-only>false</graph-read-only>
  <properties>
        <storage.backend>cassandra</storage.backend>
        <storage.hostname>127.0.0.1</storage.hostname>
        <storage.buffer-size>100</storage.buffer-size>
  </properties>
  <extensions>
    <allows>
      <allow>tp:gremlin</allow>
    </allows>
  </extensions>
</graph>
