Create or Edit a Big Object

Track and store big data that’s unique to your org. For existing big objects, a details page shows information about the big object’s fields and index.

1. From Setup, in the Quick Find box, enter Big Objects, and then select Big Objects.
2. Click New or click an existing big object.
3. Add or edit details about the big object.
4. Add or edit custom fields. Custom fields store the data for your big object records.
5. Add an index. The index defines the composite primary key for a big object and is used to query and filter the big object data.
6. Save the big object.

• Big Object Definition Details
  When you create a custom big object, several required fields define how you can access the big object.
• Custom Big Object Fields
  Custom fields store the data for your custom big object records.
• Considerations When Creating an Index
  Plan carefully when creating an index for your custom big object. The index is used for querying and filtering the big object data and must be designed properly.
• Add an Index to a Big Object
  The index defines the composite primary key for a custom big object and is used for querying and filtering the big object data. Each big object requires an index.
• Changing Big Object Fields
  Learn how big object fields differ from standard object fields when you update or delete them. Make sure that your big object is correct before you save it.
• Delete a Big Object
  When you delete a custom big object, Salesforce doesn’t add it to the Recycle Bin. Instead, deleted big objects appear in the Deleted Objects list for 15 days. During this time, the big object and its data are soft deleted, meaning you can restore or permanently erase (flag for hard delete) the big object and its data. After 15 days, the big object and its data are automatically flagged for hard delete.
