Choose Object Store v2 for keyed CloudHub integration state, budget application-wide calls and inspect value limits, partitions and lifecycle boundaries.

- Certification: Salesforce MuleSoft Platform Architect
- Exam section: Deploying API implementations to CloudHub
- Study guide: https://www.certifyforce.com/study-guide/mulesoft-platform-architect

**Official exam objective:**

> Describe the scenarios for which Object Store (OS) should be used with CloudHub.

## What the exam expects

- Choose an object store for integration state rather than treating every storage need as messaging.
- Budget Object Store v2 calls across the whole application.
- Distinguish entry limits, value limits and logical partitions.
- Inspect stored values and their lifecycle without inferring corruption from the console.

An **object store** holds keyed application state; a **partition** separates a logical key area; **TPS** measures service transactions per second; **TTL** controls an entry's lifetime; a **watermark** records synchronization progress ([Application data](https://docs.mulesoft.com/cloudhub/managing-application-data-with-object-stores), [Object Store FAQ](https://docs.mulesoft.com/object-store/osv2-faq)). This lesson concerns worker-based CloudHub and its Object Store v2 service.

## Key facts

| Fact | Detail | Source |
| --- | --- | --- |
| State examples | Synchronization progress and OAuth tokens are documented uses. | [Application data](https://docs.mulesoft.com/cloudhub/managing-application-data-with-object-stores) |
| Base rate | 10 TPS per application; every connector or API call counts. | [FAQ](https://docs.mulesoft.com/object-store/osv2-faq) |
| Premium rate | Up to 100 TPS per application. | [FAQ](https://docs.mulesoft.com/object-store/osv2-faq) |
| Value size | Each value must fit within 10 MB after Base64 encoding. | [Overview](https://docs.mulesoft.com/object-store/) |
| Store volume | Total size and number of entries are unrestricted. | [Overview](https://docs.mulesoft.com/object-store/) |
| Partitions | Logical separation does not reduce access time. | [FAQ](https://docs.mulesoft.com/object-store/osv2-faq) |
| Messaging | Use Anypoint MQ for app-to-app communication. | [FAQ](https://docs.mulesoft.com/object-store/osv2-faq) |
| Binary console value | Inspect through Object Store Retrieve before assuming corruption. | [FAQ](https://docs.mulesoft.com/object-store/osv2-faq) |

## Check yourself

- Which delimiter character must an Object Store v2 key convention avoid, and what happens to spaces?
- When Use Object Store v2 is reenabled, which condition preserves the earlier key-value pairs?
- When an automated report needs Object Store usage data, which programmatic interface should it use?
