Insertion into Graphs using txt file

[Harinath K]

Hi all . I have data set  as below in txt while which contains the transaction of users. 

# FromNodeId    ToNodeId

0                             1

0                             2

0                             3

0                             4

0                             5

1                             0

1                             2

1                            4

1                            5

1                            15

2                            0

2                             11

I need help how to create vertex and create edge between them. How can I do using program in automated way?. Node must not be repeated. any help would be useful for my project based on recommendation engine.

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
