Next conceptScatter-gather execution inside a transaction

Explainer

Scatter-Gather is a Mule router that sends one Mule event down two or more routes at the same time and then combines what each route returns. Because several routes may read the same payload, Scatter-Gather works with repeatable streams, which can be read more than once or concurrently. It does not process non-repeatable streams, which can be read only once.
Core information
  • Scatter-Gather receives a Mule event and sends a reference to that event to each route. Each route runs on its own thread, so the routes execute in parallel rather than one after another.
More details and nuances
  • Use non-repeatable-stream only when the flow reads the payload once. Scatter-Gather does not process non-repeatable streams, so a payload that feeds Scatter-Gather routes needs a repeatable strategy, which is the default.
