This document provides an example of how to use the Object Store Connector in Mule to store and retrieve data. It shows storing a Map containing key-value pairs in the object store using the <objectstore:store> element. It then retrieves the stored data using the <objectstore:retrieve> element and sets it as the payload to log and return the value.

Object store
- 1. How to use Object Store 03-04-2017
- 2. Abstract • The Object Store Connector lets you connect to the object storage facility in Mule and exposes convenient methods for exploiting the capabilities of Mule Object Stores. Internally, Mule uses object stores in various filters, routers, and other message processors that need to store state between messages.
