Salesforce Big Objects are purpose-built to handle large volumes of data-ideal for archiving long-term historical records such as 5 years of case data. They store data natively within Salesforce while minimizing impact on standard object storage limits.
Big Objects support custom definitions and can be queried using Async SOQL for efficient data retrieval.
This is well-suited for scenarios where data is infrequently accessed but must remain available for auditing or customer service inquiries. Unlike Salesforce Connect, which displays external data, Big Objects retain the data within Salesforce, which is key for compliance and availability needs.
