How do I query large objects in Salesforce?

How do I query large objects in Salesforce?

For SOQL queries with big objects, you have to build your query starting from the first field defined in the index, without skipping any fields between the first and last field in the query. So for example, if your index defines three fields, you can’t create a query using only the first and third fields.

What are Salesforce big objects?

Salesforce provides a game-changing feature within their platform called Big Objects, which provides data storage that does not count against the storage limit. These objects archive and manage massive data volumes within Salesforce without affecting performances, all with a processing scale of billions of records.

How can you make an object bigger?

Create or Edit a Big Object

1. From Setup, enter Big Objects in the Quick Find box, 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.
6. Save the big object.

How are big objects defined in Salesforce setup?

Custom big objects are defined and deployed in Setup. You can create a custom big object in Setup, where you set its definition, fields, and index. The fields defined in a big object’s index determine the big object’s identity and its ability to be queried.

Can a big object be deployed without an index?

You can’t deploy a big object until it includes an index that contains at least one custom field. Only required custom fields are allowed in an index. After you create an index, you see a second status of Deployed. Once you’re ready to grant users access, change the status to Deployed. Once you’ve defined your big object, add custom fields.

How many big objects can be created per Org?

You can create up to 100 big objects per org. The limits for big object fields are similar to the limits on custom objects, and depend on your org’s license type. Big objects don’t support transactions that include big objects, standard objects, and custom objects.

Which is the best way to process big objects?

Async SOQL is the most efficient way to process the large amount of data in a big object. While custom big objects are included with every license, Async SOQL is included only with the licensing of additional big object capacity. What’s the Catch? Because of the scale that big objects operate in, they don’t work exactly like non-big objects.
