GORM Support for Neo4j 3.0 Bolt driver

[Michael Juliano]

Hello!

Neo4j 3.0 was just released last week, and in it they introduced the Bolt binary driver. I'd like to start the conversation on adding that to GORM. I'm willing and able to contribute code to make this happen if necessary, but I'm unfamiliar with the code base, so it would take me some time.

Thanks,

Michael

Hi Michael,

We are currently still at the investigation stage for Neo4j 3 bolt support, although we are interested in talking to be people who would like to help sponsor development.

The source for the current plugin can be found here:

https://github.com/grails/grails-data-mapping/tree/master/grails-datastore-gorm-neo4j/src/main/groovy/org/grails/datastore/gorm/neo4j

The main work is to convert from using the embedded API to the Bolt driver API

See for example here:

https://github.com/grails/grails-data-mapping/blob/master/grails-datastore-gorm-neo4j/src/main/groovy/org/grails/datastore/gorm/neo4j/engine/Neo4jEntityPersister.java#L162

and here:

https://github.com/grails/grails-data-mapping/blob/master/grails-datastore-gorm-neo4j/src/main/groovy/org/grails/datastore/gorm/neo4j/engine/Neo4jQuery.groovy#L401

and here:

https://github.com/grails/grails-data-mapping/blob/master/grails-datastore-gorm-neo4j/src/main/groovy/org/grails/datastore/gorm/neo4j/engine/RelationshipPendingInsert.java#L110

etc.

Graeme
