What did you do when a optimistic locking error occurred during commit?

When an optimistic locking error (OptimisticLockException) occurs during commit, it usually means that the data we tried to update was modified by another process after we read it.

In such cases, I have used the following approaches:

• Retry the operation: after receiving the error, re-read the current data, apply changes, and try to save again. This can be implemented with a loop with a limited number of attempts.

• Improve update logic: minimize the time between reading and writing data to reduce the likelihood of conflict.

• Use versioning or timestamp in the entity to control changes.

Example in Java with JPA:

boolean updated = false;
int attempts = 0;
while (!updated && attempts < MAX_RETRIES) {
    try {
        Entity entity = repository.findById(id);
        entity.setValue(newValue);
        repository.save(entity);
        updated = true;
    } catch (OptimisticLockException e) {
        attempts++;
        // Log and retry
    }
}
if (!updated) {
    throw new RuntimeException("Failed to update data due to conflicts");
}

This approach helps to correctly handle conflicts during optimistic locking.
