I just wanted to post an update to this thread.
We have successfully run with these MariaDB versions on Camunda:
However, when we recently upgraded to Camunda 7.10.0-alpha4, we found that 10.2.13 doesn’t work.
The symptom we see is that jobs are not being picked up by the job executor.
When we try 7.10.0-alpha4 with MariaDB 10.1.x, then everything is fine.
So I think 10.2 still might have some compatibility issues. When enabling TRACE logging on the Camunda code, we didn’t see any errors, but it just wasn’t picking up the jobs. We didn’t do a lot of trouble-shooting beyond this, but I just wanted to point this out.
This related ticket, might need to be updated:
