This document provides an overview of Mule object stores, including their uses, types, and how to configure custom object stores. Mule uses object stores to persist state between messages in filters, routers, and processors. Object stores can be in-memory, persistent to filesystem, or persistent across redeployments in cloud environments. The object store connector allows storing, retrieving, listing and removing data from an object store. Custom object stores can be implemented by extending interface and classes.

MULE- OBJECT STORE Chandu Nalleboyina
OBJECT STORE It facilitates storing of objects for later retrieval. In most cases mule creates and manages object stores. You can explicitly configure an object store based on requirement. Mule uses object store in various filters, routers, and message processors that need to store their state between messages. We can create our custom stores as well for persisting objects.
USE CASES Idempotent filter. until a successful scope. Cache scope Aggregator (built-in object store or create own reference) A custom component that requires storage of objects to persist information Storing or retrieving objects from objectstore Connector
TYPES OF OBJECT STORE In-memory Store: stores object in local mule runtime memory and objects are lost on shutdown of mule runtime. Persistant store: mule persists the data when an object store is explicitly configured to be persistant In standalone mule runtime mule by default creates a persistant store in filesystem In Runtime Manager object store survives across redeployments as objects are stored in cloud but not in worker.
OBJECT STORE CONNECTOR The connector provides operations to store, retrieve, list, and remove data from a Object Store. Install object store connector from exchange Create a global configuration for objectstore <objectstore:config> refer to the global object store and perform operations using objectstore connector Operations like store,retrieve,contains,remove
SPRING BEAN INSTANCES Mule includes three default object stores instantiated every time you run mule both on premises and on Runtime Manager. _defaultInMemoryObjectStore _defaultUserObjectStore _defaultTransientUserObjectStore For cloudhub implementation of object stores we use _defaultUserObjectStore
CUSTOM OBJECT STORE Create your own object store by Implementing org.mule.api.store.ObjectStore Interface and override standard implementation of object stores like org.mule.api.store.ListableObjectStore org.mule.api.store.PartitionableObjectStore org.mule.api.store.PartitionableExpirableObjectStore
