---------------------------------
Resolution: Fixed
> 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: Improvement
> Components: came-core
> Affects Versions: 3.22.4, 4.x
> Reporter: Marcel
> Priority: Minor
> Labels: aggregator
> Fix For: 4.21.0
>
>
> 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.
