a.k.a. “unmanaged extensions”
“Stored procedures” on steroids
Implemented and tested (!) in Java
Deployed with Neo4j (same lifecycle)
Custom APIs - What?

6. GraphAware
TM
Access to native Neo4j API (Java)
Performance
Locking
Too complex for Cypher
Functions missing in Cypher
Custom input/output format
Limit to read-only
Code to Data
…
Custom APIs - Why?

7. GraphAware
TM
GraphAware Framework makes it extremely easy
to build, test, and deploy custom Neo4j APIs.
Custom APIs (How?)

8. GraphAware
TM
pure Spring MVC
test with GraphUnit
drop to plugins
restart Neo
Custom APIs - How? (GraphAware)

9. GraphAware

representing time in Neo4j
storing and querying time series data
GraphAware TimeTree
Custom APIs - Example

10. from: "..@.."
to: "..@.."
text: "…"

Neo4j is fully ACID
“Triggers” on steroids
Implemented and tested (!) in Java
Transaction-Driven Behaviour - What?

14. GraphAware
TM
Integrations with other systems
In-graph indexing
Additional modifications
Schema enforcement
Transaction-Driven Behaviour - Why?

15. GraphAware
TM
GraphAware Framework makes it extremely easy
to build, test, and deploy custom Transaction-
Driven functionality.
Transaction-Driven Behaviour (How?)

16. GraphAware
TM
Tracking changes in your graph (demo)
Assigning a UUID to each node (demo)
Defining and enforcing constraints (wip)
Auditing
…
Transaction-Driven Behaviour - Examples

19. GraphAware
TM
Neo4j is primarily OLTP
Requests drive transactions
How about background computation?
Asynchronous Computation - What?

20. GraphAware
TM
Interesting graph algorithms
Expensive in real-time
Can be approximate
Can be approximated
There are quiet periods / dedicated slaves
Asynchronous Computation - Why?

21. GraphAware
TM
GraphAware Framework makes it possible to
build, test, and deploy functionality executed in
the background during quiet periods.
Asynchronous Computation (How?)

22. GraphAware
TM
Page Rank
Recommendations
Similarities
Centralities
Statistics
…
Asynchronous Computation - Examples

GraphAware Framework makes it easy to build,
test, and deploy generic as well as domain-specific
functionality for Neo4j.
