# Aggregators Module 1.1

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

For compatibility information and fixed issues, see the Aggregator Module Release Notes.

Aggregators Module contains different types of aggregators that use a specified configuration to
both store and release values. An _aggregator scope_ is a component that collects those values until
a specified condition is met, when it then executes a processor’s chain of components, with the list
of aggregated elements as the payload.

The basic aggregator configuration consists of the definition of the value to aggregate (extracted
from the message through an expression evaluation), a condition that defines when the aggregation is
considered complete, and a processor chain that executes once that condition is met.

Aggregators are pass-through routers. The same data that an aggregator scope receives is processed
by the components that follow the aggregator scope. The only modification is variable propagation if
any variables are set during the execution of any of the aggregation routes.
