JetBrains Xodus is a transactional, schema-less embedded database written in Java and Kotlin, offering ACID transactions with MVCC and snapshot isolation. It powers JetBrains YouTrack and Hub and provides both key-value (Environments) and entity-store APIs.

Use cases

• embed an ACID database in a JVM application
• schema-less key-value storage with no administration
• highly concurrent non-blocking reads via MVCC
• store entities without schema migrations
• embedded persistence for issue tracking or user management tools

When to choose

• you need an embedded, zero-administration database inside a Java/Kotlin app
• you want fully ACID transactions with non-blocking snapshot-isolated reads
• your data model changes often and you want to avoid schema migrations

When to avoid

• you are starting a new project - the project is in sunset stage in favor of YouTrackDB
• you need a client-server or networked database
• you need rich query languages, joins, or SQL support
