------------------------------
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.
