I wonder if there's a design decision documented somewhere that makes the existing graph databases like Neo4j, etc. not good enough for Youtrack's use case.

zihotki•13m ago

That's a good question indeed. Also I wonder why they picked java as the implementation language.

rednb•5m ago

Likely because they are a Java shop. All the IDEs they develop use Java, so they have quite an expertise in low level optimization for this language.

Neo4j license price is egregious for enterprise customers. A few years ago I was involved in negotiating a contract for a small/medium size deployment (think 15-25 cores) and the annual price was more than the salary of senior SWE full-time equivalent.
