Somewhat related to this question, is it possible to use ChronicleMap to capture a property graph as a memory-mapped file? Currently we are hosting our graph in AWS Neptune, but would like to query it locally, but off-heap, on each of our (Java) application servers.

If you have a graph database, you could use neo4j as I believe it stores data off heap.
Chronicle Map is designed for key-value pairs, where the keys and values can be efficiently serialized independently as tree structures. i.e. they can't have circular dependencies.

Thanks. Our goal is to export and memory-map the graph locally on the client, and as such we are trying to see if any system already exists that enables this. Neo4j utilizes memory-mapping, but it's done on the server itself so it doesn't really apply here. – Kevin Dec 06 '18 at 22:47

@Kevin if you can structure the data as key-value pairs, Chronicle Map will do what you want. – Peter Lawrey Dec 07 '18 at 08:00

yes i've thought about that but was exploring all other possible options first - haven't yet dived into what the complexity would be to convert the graph to key-value pairs. – Kevin Dec 07 '18 at 16:25
