Hi Arinath,

if it's just a one-shot batch insert, you can write a simple Java program and use OGraphBatchInsertBasic class, that is specifically designed for this simple use case.

Otherwise you could think about using OrientDB ETL and define a simple importer from CSV, see http://www.orientechnologies.com/docs/last/orientdb-etl.wiki/Introduction.html

Of course, doing the same in Java using Graph API would be a matter of a few lines of code, if you need help on this just let as know

Luigi
