Hi everyone,

It's been a while since our last version announcement and today I'm happy to share with you v0.16, which includes some very exciting improvements for Atlas:

• ClickHouse Beta Support - ClickHouse is a high-performance, columnar database optimized for analytics and real-time query processing. Support for ClickHouse in Atlas has been one of the top requested features by our community in the past year. Today, we are happy to announce that ClickHouse is officially in Beta!
• Hibernate Provider - Atlas now supports loading the desired state of your database directly from your Hibernate code. Hibernate developers can now join developers from the GORM, Sequelize, TypeORM and more communities who can now use Atlas to manage their database schema.
• Baseline Schemas - In some cases, your migrations rely on certain database objects to exist apriori to your application schema, for example extensions or legacy tables. Atlas now supports defining a baseline schema which will be loaded before automatically planning and applying your migrations.
• Proactive conflict detection - Teams that have connected their project to Atlas Cloud will get a prompt in the CLI if their migration directory is out of sync with the latest version in Atlas Cloud. This ensures that new migration files are added in a sequential order, preventing unexpected behavior.
• Mermaid Support - Atlas now supports generating a Mermaid diagram of your database schema. This is a great way to visualize your database schema and share it with your team.
• Review Policies - Users working with declarative migrations can now define "review policies" which can define thresholds for which kinds of changes require human review and which can be auto-applied.
• Postgres Sequences - Another long awaited feature, Atlas now supports managing sequences in PostgreSQL.

I know that's quite a list, so let's dive right in!

Introduction​

Hibernate-ORM is one of the most popular ORMs for Java, so much so that parts of it have evolved into the JPA standard and the Jakarta APIs.

Today, we are excited to announce that Atlas now supports loading and managing Hibernate schemas.

Atlas is a modern tool for managing your database schema. It allows you to inspect, plan, lint and apply schema changes to your database. It is designed to be used by developers, DBAs and DevOps engineers alike.

By using Atlas, Hibernate users can now enjoy these benefits:

• A declarative migration flow - Atlas can operate like a "Terraform for databases", where by running atlas schema apply the application schema is applied on a target database.
• Automatic schema migration planning - Alternatively, Atlas can operate using a more traditional versioned migration flow. However, contrary to most tools, Atlas will automatically analyze the diff between the migration directory and the current application data model, and will produce correct and safe SQL migration files.
• CI for schema changes - Atlas can be used during CI to make sure you never merge a pull request that will break your database schema.
• Modern CD integrations - Atlas integrates seamlessly with modern deployment tools such as Kubernetes, Terraform, Helm, Flux, and ArgoCD. This allows you to deploy changes to your database schema as part of your existing deployment pipelines.
• Visualization - Atlas users can create beautiful, shareable ERDs of their application data model with a single command.
