             Summary: AggregateProcessor: Add configuration option for synchronous Optimistic Locking retry behavior
                 Key: CAMEL-23352
                 URL: https://issues.apache.org/jira/browse/CAMEL-23352
             Project: Camel
          Issue Type: New Feature
          Components: came-core
    Affects Versions: 3.22.4, 4.x
            Reporter: Marcel
             Fix For: 4.x


Currently the AggregateProcessor performs Optimistic Locking retries asynchronously
in a separate thread (behavior introduced in Camel 3.x). In Camel 2.x the retries
were synchronous.

This change broke use cases where the aggregator is used together with a persistent
aggregation repository inside a transaction. In such setups, a synchronous answer
from the aggregator is required to decide whether to commit or roll back the
currently open transaction.

We propose adding a configuration flag to AggregateProcessor (e.g.
optimisticLockingSynchronous=true/false) to allow users to choose between
synchronous and asynchronous Optimistic Locking retry behavior.

We are prepared to provide a PR implementing this option.
