This project is entering its SUNSET stage as we embark on an exciting migration to our new YouTrackDB graph database. Stay tuned for upcoming announcements, detailed plans, and migration guidelines as the YTDB project unfolds. JetBrains Xodus is a transactional schema-less embedded database that is written in Java and Kotlin. It was initially developed for JetBrains YouTrack, an issue tracking and project management tool. Xodus is also used in JetBrains Hub, the user management platform for JetBrains' team tools, and in some internal JetBrains projects. - Xodus is transactional and fully ACID-compliant. - Xodus is highly concurrent. Reads are completely non-blocking due to MVCC and true snapshot isolation. - Xodus is schema-less and agile. It does not require schema migrations or refactorings. - Xodus is embedded. It does not require installation or administration. - Xodus is written in pure Java and Kotlin. - Xodus is free and licensed under Apache 2.0. Hello Worlds!
