Which type of object store can share state between components in a Mule application?

The global object store is designed to enable sharing state among various components within a Mule application. This means that any component, regardless of its location or execution context within the application, can access and manipulate the data stored in the global object store.

This capability is particularly useful for scenarios where different parts of the application need to maintain and access the same dataset, such as caching configuration settings, maintaining user sessions, or sharing information between different flows. The global object store facilitates this shared access, ensuring consistency and availability across various components involved in the business logic.

In contrast, the private object store is limited to a single flow, meaning data stored there is not accessible outside of that specific flow's context. The transient object store is typically used for temporary data that does not need to persist beyond the current execution of the application. The local object store is meant for a single instance of a flow and does not allow for sharing state across multiple components or flows within the application. Hence, the global object store is the only choice that provides the necessary functionality for sharing state effectively.
