be slower than simply using the core API, so if speed and performance are of the utmost

importance to you, you might be better served using the native API.

Note

The SDN framework provides a number of hooks (code providing access to the underlying

GraphDatabaseService instance), which, if required, allow you to drop down and

use the low-level core APIs to achieve maximum performance and flexibility. You can still

view, query, and (with certain restrictions applied) update the graph outside of SDN using

standard Neo4j tools if you so desire. Later in this chapter, the sidebar “ Can SDN and Nat-

ive Neo4j play nicely together? ” offers more information on this subject.

9.1.4. Where to get more information

SDN is a vast project in and of itself, and we'll only be able to go so far in covering it

here. In this chapter we aim to provide an introduction to some of the important aspects

in the framework rather than a comprehensive reference guide. If you're looking for more

in-depth coverage on any of the points covered here, as well as those we'll not be able

to cover, there are good topics on this subject, namely Good Relationships by Michael

Hunger, which has also been incorporated into the official SDN reference docs, avail-

load at www.infoq.com/minibooks/good-relationships-spring-data ) and Spring Data by

Mark Pollak and others (O'Reilly, 2012). In general, the SDN documentation ( ht-
