Hi lucky dog,

Thank you for the bug report. It seems like Camunda only supports the loadbalance mode. I will forward this ticket for scheduling.

In the meantime, feel free to submit a PR that fixes this issue.

Best,
Nikola

I found that failover is the alias of loadbalance, and I concurrently tested that my flow (including message events, tiemer events) is normal in sequential mode, why do you say Camunda only supports the loadbalance mode?

Hey lucky dog,

Sorry, I completely mixed up the modes in my last reply. I missed the MariaDB docs statement that failover is the alias of the loadbalance mode:

loadbalance mode docs: Before 2.4.2, this option was named `failover` - alias still exist for compatibility

In this case, the bug is that we need to clarify the documentation that Camunda supports the loadbalance and sequential modes since failover is an alias of loadbalance. We also need to remove loadbalance from the list of unsupported modes.

However, it's still unclear why the Camunda docs state the loadbalance and failover modes as separate. Maybe at some point, they were, so this needs to be confirmed before changing the docs.

Best,
Nikola

The URL format I use: JDBC: MariaDB: failover://192.168.1.1:32980192.168.1.2:32980192.168.1.3:32980 / process engine,

I designed a BPMN process, which includes message events and message Association operations, and then I had a deadlock during the concurrent test.
