A Mule application is built to support a local transaction for a series of operations on a single database. The Mule application has a Scatter-Gather that participates in the local transaction.
What is the behavior of the Scatter-Gather when running within this local transaction?
In the context of Mule applications, a Scatter-Gather processes routes in parallel by default. When it comes to local transactions, if an error occurs within any route of the Scatter-Gather, it will indeed result in a rollback of all database operations to maintain data integrity. Therefore, the correct behavior is parallel execution with rollback on error.
