Key changes
Data
RDBMS secondary storage
Camunda 8.9 introduces optional RDBMS secondary storage as an alternative to Elasticsearch or OpenSearch.
This enables teams to use relational databases such as H2, PostgreSQL, Oracle, or MariaDB for storing and querying process data, reducing operational complexity for non-high-performance use cases.
To learn more, see the 8.9.0-alpha1 release notes.
MySQL and Microsoft SQL Server secondary storage support
Camunda 8.9 extends RDBMS secondary storage to include MySQL and Microsoft SQL Server as additional options for the Orchestration cluster.
To learn more, see the 8.9.0-alpha1 release notes.
Deployment
Standardized JDBC driver management for RDBMS
Camunda 8.9 adds a standardized JDBC driver management system for manual installations.
- A new
/driver-libdirectory separates Camunda-bundled drivers from customer-supplied ones. - Customers can add and configure their own drivers (for example, Oracle JDBC), while maintaining full compliance and version control.
To learn more, see the 8.9.0-alpha1 release notes.
Modeler
Web Modeler: RDBMS support (H2, MariaDB, MySQL)
Camunda 8.9 adds support for H2, MariaDB, and MySQL as relational databases for Web Modeler.
This enhancement aligns Web Modeler’s database configuration with the Orchestration cluster, ensuring consistent setup and improved integration across environments.
