# Object Store v2 and persistent stores by deployment

*MuleSoft Platform Integration Architect Study Guide · Designing integration solutions to meet persistence requirements · Last updated November 13, 2026 · https://www.certifyforce.com/study-guide/mulesoft-platform-integration-architect/designing-integration-solutions-to-meet-persistence-requirements/object-store-v2-and-persistent-stores-by-deployment*

Where an object store actually keeps its data on CloudHub 1.0, CloudHub 2.0, Runtime Fabric and an on-premises cluster, and the Object Store v2 limits, billing, security and control-plane rules that decide whether it fits a design.

- Certification: Salesforce MuleSoft Platform Integration Architect
- Exam section: Designing integration solutions to meet persistence requirements
- Study guide: https://www.certifyforce.com/study-guide/mulesoft-platform-integration-architect

**Official exam objective:**

> Design Mule applications using Object Stores (OSs), the OS Connector, and OS services in all deployment options.

## What the exam expects

- Choose the store that keeps data across restarts and replicas on CloudHub 1.0, CloudHub 2.0, Runtime Fabric, standalone runtimes and on-premises clusters.
- Apply Object Store v2 limits (TTL, entries, keys, values, transactions) and its billing rules to a design.
- Recognize where Object Store v2 is available by control plane and what to deploy to instead.
- Plan Persistence Gateway on Runtime Fabric and explain how the Object Store Connector reaches it.
- Predict object store behavior under the Quorum Protocol, and decide when values need application-side encryption.

**Object store:** a facility Mule uses to persist data for later retrieval ([Object stores](https://docs.mulesoft.com/mule-runtime/latest/mule-object-stores)). **Object Store v2:** the CloudHub service that stores data and states across batch processes, components and applications ([Object Store v2 Overview](https://docs.mulesoft.com/object-store/)). **Persistence Gateway:** Runtime Fabric's store shared across replicas and restarts ([Persistence Gateway](https://docs.mulesoft.com/runtime-fabric/latest/persistence-gateway)). **TTL:** time to live, after which an entry is evicted.

## Check yourself

- Why does enabling Object Store v2 for a Mule 4 CloudHub application change where its default persistent store writes?
- When Use Object Store v2 is disabled and later reenabled for a CloudHub application, what happens to the stored pairs?
- How many billable units does storing one 250 KB value count?
- Which minimum Mule Maven plugin version can enable persistent object stores for Runtime Fabric deployments?
