Optimistic locking exception retry customization

[FilipGregor]

We are using camunda 7.7.0. Is there o way for me to customize number of retrys when Optimistic locking exception occures? If this exception occures i want to try only once then fail with exception.

@FilipGregor if Optimistic locking exceptions occurred in service tasks or with any async boundaries executions which are in camunda job executor scope will be auto retried with 3 times. For implementing custom retry mechanism for this exception you can try below:

Why does a deadlock occur on completing an external task? And how to retry it?

We use the Spring Retry logic to have several attempts on OptimisticLockingExceptions and deadlocks before a failure is returned. Since deadlocks in the database are not thrown as specific exceptions, I figured out to ‘catch’ them within a custom RetryPolicy: public class NextRetryPolicy extends SimpleRetryPolicy { private final static NextLogger LOGGER = NextLogger.RETRY_LOGGER_INSTANCE; public NextRetryPolicy(int maxAttempts) { // Instantiate super class with OptimisticLockingException…

if Optimistic locking exceptions occured in User Task type then you can try with implementing Spring Rest Template retry.
