Custom APIs

Transaction-Driven Behaviour

Asynchronous Computation

Advanced Use Cases

GraphAwareTM

a.k.a. “unmanaged extensions”

“Stored procedures” on steroids

Implemented and tested (!) in Java

Deployed with Neo4j (same lifecycle)

Custom APIs - What?

GraphAwareTM

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?

GraphAwareTM

GraphAware Framework makes it extremely easy to build, test, and deploy custom Neo4j APIs.

Custom APIs (How?)

GraphAwareTM

pure Spring MVC

test with GraphUnit

drop to plugins

restart Neo

Custom APIs - How? (GraphAware)

GraphAwareTM

representing time in Neo4j

storing and querying time series data

GraphAware TimeTree

Custom APIs - Example

from: "..@.."to: "..@.."text: "…"

Advanced Use Cases

GraphAwareTM

Neo4j is fully ACID

“Triggers” on steroids

Implemented and tested (!) in Java

Transaction-Driven Behaviour - What?

GraphAwareTM

Integrations with other systems

In-graph indexing

Additional modifications

Schema enforcement

Transaction-Driven Behaviour - Why?

GraphAwareTM

GraphAware Framework makes it extremely easy to build, test, and deploy custom Transaction-Driven functionality.

Transaction-Driven Behaviour (How?)

GraphAwareTM

Tracking changes in your graph (demo)

Assigning a UUID to each node (demo)

Defining and enforcing constraints (wip)

Auditing

…

Transaction-Driven Behaviour

Asynchronous Computation

Advanced Use Cases

GraphAwareTM

Neo4j is primarily OLTP

Requests drive transactions

How about background computation?

Asynchronous Computation - What?

GraphAwareTM

Interesting graph algorithms

Expensive in real-time

Can be approximate

Can be approximated

There are quiet periods / dedicated slaves

Asynchronous Computation - Why?

GraphAwareTM

GraphAware Framework makes it possible to build, test, and deploy functionality executed in the background during quiet periods.

Asynchronous Computation (How?)

GraphAwareTM

Page Rank

Recommendations

Similarities

Centralities

Statistics

…
