# Zones

Many Data Generator Tasks emit new data known as `zones`. These `zones` can be interpreted as context-based data by creating an execution context and injecting it into tasks that can be the starting point of an workflow (mostly related to events). This serves as a way to segment the information and make sure that the data belonging to the same `zone` can continue in the flow.

Several tasks are configured to use `zones`:
