Cypher vs Java API

[Sotiris Beis]

Hi all,

I am wondering which is better to use in terms of performance and features. Keep in mind that I am building a Java app and I can use Cypher only via ExecutionEngine or if I use neo4j-spring-data. So it would be much appreciated if you can answer the following questions.

- Which one is the fastest for  my use case?

- Both have the same features? I can't find a way to query the graph with regular expressions as described here using the Java API. Is it something the is not supported from Java API?

- Is there any extra overhead when using neo4j spring data?

- Can I access my graph with spring data if the has been build with a python etl script? I've tried some examples and I get this exception: 

No primary SDN label exists .. (i.e one starting with _)

It seems that a spring metadata value missing.

Thanks in advance,

Sotiris

Depends on your use-case which one is faster, currently you can tune the Java API better but going forward (2.3+) it is very likely that cypher will be faster.

Get the string property and compare it with string.matches("regexp")

Yes as SDN adds an indirection layer there is overhead managing the graph in a convenient manner.

For SDN3 you'll have to add metadata to the graph with template.postEntityCreation(node/rel, DomainEntity.class)

In terms of performance how is spring data neo4j?
