Insert data back into Neo4j table

I'm newbie in Datacleaner. I created a datastore based on Neo4j connection which work fine, I did my transformation but I wasn't able to insert data back to a new table in neo4j in the "write" module. there are few options (h2, ...) but nothing for Neo4j.

Does someone faced the same and what I'm missing here ?

Hi Arcondo,

Unfortunately the Neo4j datastore is not a writable datastore, so it can only be used for querying, not for updating the datastore.

We're using Apache Metamodel for reading and writing data, so to get that changed someone would have to implement writing to MetaModel's Neo4jDataContext, but since Neo4j is so different from the general data model used by MetaModel and DataCleaner I imagine that's not a small change. If you feel like giving it a shot, contributions to MetaModel are always appreciated. Otherwise maybe add a feature request to the MetaModel JIRA.
