Support RDBMS as secondary storage for Dual Region in Camunda 8

[Shunxiang_Yao]

Hi:

I understand at the moment from the documentation “Dual-region configurations don’t support OpenSearch or RDBMS (relational database) secondary storage.”

Just wondering if Camunda has any plans to support RDBMS as secondary storage for Dual Region in the near future?

We hope to use dual region for C8 and already have the RDBMS setup (one DB instance in each region, replicated between them and can be accessed via LoadBalancer url or DNS directly) so it’ll be easier for us. Thanks.

Best regards
Shunxiang

Currently dual-region configurations only support Elasticsearch as secondary storage (not OpenSearch or RDBMS), and there’s no confirmed timeline yet for RDBMS support in dual-region, though there’s active roadmap work on RDBMS capabilities. I found the following relevant resources:

• Dual-Region requirements
• Dual-Region architecture
• RDBMS Helm chart limitations
• RDBMS production architecture
• Roadmap: Run Orchestration Cluster with RDBMS using Helm charts
• Roadmap: Data migration in Camunda 8 from Elasticsearch to RDBMS
• Roadmap: Relational database support for secondary data store

Does this help? If not, can anyone from the community jump in?
