RDS Change Data Capture to Neo4j

I have a main DB as RDS, want to move CDC data to Neo4j. What are my options, currently we are loading CDC from RDS to Kafak and then post to REST service which posts to Neo4J. This is not performing as expected

i am trying to look at other options
Did anyone has a similar approach? Trying to look to work with Google DataFlow? and directly write from kafka to Neo4J

Any suggestions or pointers will be helpful
