MongoDB & how to use PersistenceSession

[Thomas Auinger]

Hi,

 

two questions:

 

1.       Has anybody used some NoSQL database with the camunda engine, especially Mongodb? Alternatively neo4j as a graph DB?

2.       I know that the persistence layer has been rewritten in 7.2 – but how would I make use of a custom PersistenceSession implementation? What’s the reason that setSessionFactories() is not part of the ProcessEngineConfiguration interface?

 

Thanks guys!

Thomas

Hi Thomas,

Not sure about MongoDB and neo4j, but there is a community extension implementing persistence on top of Cassandra that you might find interesting [1].

Regarding your second question: ProcessEngineConfiguration is public API [2] for which we provide certain stability guarantees with future releases. That does not hold for the SessionFactory interface, so the method #setSessionFactories is not part of the public API interface.

Cheers,
Thorben
