Integrating Neo4j with DynamoDB

We are running an amazon hosted Neo4j cluster and we are getting close to 30G of data, storing quite a lot of legal documents with some hefty fulltext properties that tend to take a lot of space. We are now starting to experience instability around backups as well as some very slow queries, so we are considering moving the fulltext properties to DynamoDB and keeping the relationships and shorter properties in Neo4j.
Is this something that there is experience with in the Neo4j community? I know running an Elasticsearch integration was common at least before native fulltext indexes - would it be possible to keep DynamoDB in sync with the Neo instance using some of the same approaches?
