BLURB:

eProsima Fast DDS implements the RTPS (Real Time Publish Subscribe) protocol, which provides publisher-subscriber communications over unreliable transports such as UDP, as defined and maintained by the Object Management Group (OMG) consortium. RTPS is also the wire interoperability protocol defined for the Data Distribution Service (DDS) standard. eProsima Fast DDS expose an API to access directly the RTPS protocol, giving the user full access to the protocol internals.

summary

* AFAICT, this is not (yet) in active use in production YouTrack, which is still using https://github.com/JetBrains/xodus

* the technical leader of the YouTrackDB project, Andrii Lomakin, was one of the main contributors to OrientDB -- see https://medium.com/@youtrackdb

* YouTrackDB is a fork of OrientDB

* this project makes heavy use of Claude Code

* YouTrackDB does not use Kotlin

* this can be used as a network service (rather than just embedded in a single runtime process like in current production YouTrack), but I've not yet got the docker images working to try.

from the blurb

YouTrackDB is a general-purpose object-oriented graph database developed by JetBrains, used internally in production. It implements the Apache TinkerPop API with Gremlin query language support and features O(1) link traversal, schema-less/mixed/full modes, and encryption at rest. The project is a fork of OrientDB, re-architected under the com.jetbrains.youtrackdb package namespace.
