Titan batch graph

Question

I want to add a new Property [and some times add edges] to a selection of nodes in an existing Graph of 2 million nodes, 10+ million edges. I thought of using BatchGraph but from their WIKI looks like it does not support any retrieval queries.

For e.g. retrieve these nodes: g.V('id',1).has('prop1','text1') and update 'prop1' to 'text2'.

What is the best way to do this.

Answer 1

I don't think you need to use BatchGraph here. It sounds as if you are doing a large graph mutation in which case it would probably best to just write a Gremlin script to do your changes. You don't have a very large graph so unless you plan to do some very complex mutations (e.g a fat multi-step traversal), it shouldn't take very long to execute. If you do think it's going to run "long" you should think of ways to parallelize the job. If you go this route you might consider using gpars.

As your graph grows, you will find that you will need to use Faunus for most data administration. Specifically, that means utilizing script step.
