Batch insertion in Neo4j

votes

I am new to neo4j. I have created graph database in neo4j i.e "my.graphdb" which also include schema indexes. Now I want to use this database into my java program. For that I used batch insertion. Also I am creating schema indexes in my java program. But when I run the program it gives me following exception.

Exception : 

java.lang.UnsupportedOperationException: Schema modification is currently not available

through the BatchDatabase API.

In short, I want to use my existing graph database (my.graphdb) into new java program. Moreover, I want to use my existing data and indexes present in my.graphdb to insert new nodes and relationships.

Please let me know what should I do ?

Your question is confusing, can you detail the steps you took and show code / setup? And also share the full stack trace and the place where it occurred. - Michael Hunger

The BatchGraphDatabase should not be used.

Use the BatchInserter or the transactional EmbeddedGraphDatabase.

The Batchinserter also supports the creation of schema indexes which are populated at shutdown (test with a small dataset first, it can take a while, will be faster in 2.0.1).
