# Salesforce High-Scale Objects

Use high-scale objects when you have a large number of transactions, large objects, or you must store data over a long period. These objects sometimes have different limitations, APIs, or querying behavior than Salesforce common objects do.

## Big Objects

**Usage:** Auditing, tracking, feeds, and historical archives.

**Transaction Type:** OLTP transactions

**Database Storage:** Horizontally scalable distributed databases that are non-transactional and scale to hundreds of millions or even billions of records. Big objects can contain data that’s larger than the data that Data Cloud or standard objects support.

**Object Type:** BO

**Object Suffix:** \_\_b

**Customizable:** Yes

**Cloud:** Any cloud that provides an org. However, Big Objects requires an additional license.

**Packaging:** Use the deploy() and retrieve() calls to deploy and retrieve a .zip file. Standard AppExchange packaging isn’t available.

**Object Examples:** [FieldHistoryArchive](https://developer.salesforce.com/docs/atlas.en-us.264.0.object_reference.meta/object_reference/sforce_api_objects_fieldhistoryarchive.htm)

**Documentation:** [Big Objects Implementation Guide](https://developer.salesforce.com/docs/atlas.en-us.264.0.bigobjects.meta/bigobjects/big_object.htm)

**Reference:** [Object Reference for the Salesforce Platform](https://developer.salesforce.com/docs/atlas.en-us.264.0.object_reference.meta/object_reference/sforce_api_objects_list.htm)

## High-Scale Order Objects

**Optimized for:** OLTP transactions

**Objects:** PendingOrderSummary

**Documentation:** [Order Management Implementation Guide](https://help.salesforce.com/s/articleView?id=commerce.om_impl_intro.htm&type=5&language=en_US)

**Reference:** [Object Reference for the Salesforce Platform](https://developer.salesforce.com/docs/atlas.en-us.264.0.object_reference.meta/object_reference/sforce_api_objects_pendingordersummary.htm)

## Data Cloud Objects

**Optimized for:** OLAP transactions

**Object types:** DLO, DMO, CIO, DG

**Documentation:** [Data Object Concepts and Schema in Data Cloud](https://help.salesforce.com/s/articleView?id=data.c360_a_schema_setup_concepts.htm&type=5&language=en_US)

- **[Salesforce Data Cloud Objects](https://developer.salesforce.com/docs/atlas.en-us.object_reference.meta/object_reference/sforce_api_concepts_data_cloud_objects.htm)**  
    Data Cloud objects are high-scale objects that are used to store large amounts of data over time.
