Task Description

Due to many problems in using OrientDB, it was decided to switch to another database. JanusGraph was chosen as a new database.
As part of the PoC project we developed the core concept of Domain Model implementation based on TinkerPop and Spring Data Neo4j. All persistence of Strongbox should be reworked follwing way:

  • Domain Entities should have interfaces (this is needed to support inheritance, which is not supported by JanusGraph out of the box)
  • Every Domain Entity should have EntityTraversalAdapter implementation (needed to provide CRUD traversals for the entity)
  • Every entity should have Repository based on GremlinRepository
  • All CRUD operations in repository should be implemented with EntityTraversalAdapter
  • Cypher can be used for custom queries with Spring Data Neo4j

@sbespalov .

Here are my findings...

Building strongbox against strongbox locally (via mvn spring-boot:run in the strongbox-web-core) eventually fails with the attached logs. Part of the build passes, but then it suddenly crashes.

Here are the logs:

In addition, the build is quite sluggish... I assume this has something to do with all the writes going on...?

@carlspring could you please clarify what it means?

I don't have the log files in front of me right now, but I believe that there were failing transactions while writing (?)...

Hi guys, OrientDB has a successor and its name is ArcadeDB. It's much faster, lighter, 100% java (no JNA/JNI), and supports the same SQL from OrientDB (it's actually the only piece of SW we copied). It supports also Gremlin (the latest version), Cypher, and much more. Also used embedded has minimal dependencies, the entire engine is a few MB.

I am the original author of OrientDB and now working on ArcadeDB. OrientDB was dead in the water a long time ago, the future is ArcadeDB. We're helping many projects with this switch. If you guys are interested I'd love to create a POC for StrongBox and eventually a PR.

Cheers,
Luca
