Description
Expected Behavior
We are using Temporal 1.20 with MariaDB 10.2.30 and now we moved to new MariaDB 10.6.9 running in clustered mode (using Galera https://galeracluster.com/)
Actual Behavior
Testing with new Version we observe issues on some workflows, workflow stays in status "Running", activity is scheduled but nothing happens.
Steps to Reproduce the Problem
- use MariaDB 10.6.9
- launch e.g. 100 workflows
- some workflows stay in status RUNNING forever
Specifications
- Version: 1.20
- Platform: K8S

Research direction
Start by reproducing the issue with Temporal 1.20, MariaDB 10.6.9 in a Galera cluster, Kubernetes, and about 100 workflows. Compare the behavior with MariaDB 10.2.30 and non-clustered operation, then trace the affected workflow and activity execution path. Done means the cause is identified and workflows no longer remain running indefinitely.
