Big objects capture data for use within Force.com and are accessible via a standard set of APIs to clients and external systems. What differentiates big objects is that they have been built to provide consistent performance whether there is 1 million records, 100 million, or even 1 billion records. This scale is what gives big objects their power and what defines the features that are provided.

Performance, Unlimited, and Developer Editions

There are two types of big objects.

•

Standard big objects — Objects defined by Salesforce and included in Salesforce products.

FieldHistoryArchive

is a standard big object that stores data as part of the Field Audit Trail product.

•

Custom big objects — New objects that you create to store information unique to your org. Custom big objects extend the functionality that Force.com provides. For example, if you’re building an app to track product inventory, create a custom big object called

HistoricalInventoryLevels to track historical inventory levels for analysis and future optimizations.

Custom Big Object Use Cases

•

360° view of the customer — Extend your Salesforce data model to include detailed information from loyalty programs, e-commerce transactions, billing and provisioning information, and more.

•

Auditing and tracking — Track and maintain a long-term view of your user’s usage of Salesforce or your customer’s usage of your products for analysis or compliance purposes

•

Historical archive — Maintain access to historical data for analysis or compliance purposes while optimizing the performance of your core CRM or Force.com applications.

Considerations

•

Big objects support only object and field permissions.

•

You must use the Metadata API to define a big object or add a field to a custom big object.

•

SOQL relationship queries are based on a lookup field from a big object to a standard or custom object in the select field list (not in filters or subqueries).

•

Big objects support custom Lightning and Visualforce components rather than standard UI elements home pages, detail pages, list views, and so on).

•

You can create up to 100 big object 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 including both big objects, standard object and custom objects.

•

To support the scale of data in a big object, features like triggers, flows, processes, and Salesforce1, are not available.

Define a Custom Big Object

Available in: Enterprise,

Performance, Unlimited, and Developer Editions

To use file-based Metadata API calls, define a custom big object by creating XML files that contain the definition, fields, and composite primary key (index) for the custom big object.

You define a custom big object by creating an XML file that contains its definition, fields, and index.

•

object

files—Create a file for each object to define the custom big object, it’s fields and it’s index.

•

permissionSet

/ profile

files—Create a permissionSet or profile file to specify permissions for each field. These files are not required, but is required to grant access to users. By default, access to a custom big object is restricted.

•

package

file—Create a file for the metadata package to specify the contents.

Note: While custom big objects use the “CustomObject” metadata type, some parameters are unique to big objects and others are not applicable. The specific metadata parameters that apply to big objects are outlined in this document.

Naming Conventions for Custom Big Objects

Object names must be unique across all standard objects, custom objects, external objects, and big objects in the org. In the API, the names of custom big objects are identified by a suffix of two underscores immediately followed by a lowercase “b” (__b). For example, an external object named “HistoricalInventoryLevels” is seen as HistoricalInventoryLevels__b in that organization's WSDL. We recommend that you make object labels unique across all objects in the org - standard, custom, external and big objects.

Deploy Custom Big Objects as a Metadata Package

Use the Metadata API to deploy a custom big object. You can use several different tools, like Workbench or the Ant Migration Tool, to deploy.

Big Objects Define and Deploy Custom Big Objects

Note: You can run a test deployment by using the checkOnly

deployment option. In Workbench, select the Check Only option on the Deploy screen.

View a Custom Big Object in Setup

After you’ve deployed your custom big object, you can view it by logging in to your organization and, from Setup, entering

Big

in the

Quick Find

box, then selecting Big Objects.

Click the name of a big object, to see its fields and relationships.

Big Objects Populate a Custom Big Object

Populate a Custom Big Object

Use Salesforce APIs to populate a custom big object.

You can use a CSV file to load data into a custom big object via SOAP API Bulk API. The first row in the CSV file must contain the field labels used to map the CSV data to the fields in the custom big object during import.

Re-inserting a record with the same index but different data results in behavior similar to an upsert operation. If a record with the index exists, the insert overwrites the index values with the new data. Insertion is idempotent, so inserting data that already exists won't result in duplicates. Reinserting is helpful when uploading millions of records. If an error occurs, the reinsert reuploads the failed uploads without duplicate data. During the reinsertion, if no record exists for the provided index, a new record is inserted.

For example, this CSV file contains data for import into a Customer Interaction big object.

Populate a Custom Big Object with Apex

Use Apex to populate a custom big object.

You can create and update custom big object records in Apex using the insertImmediate

method.

Warning:

Any Apex tests that use DML calls will fail and potentially insert bad data into the target big object. This data won’t be deletable. To test DML calls, use a mocking framework with the Apex stub API to contain calls to the target big object.

Here is an example of an insert operation in Apex that assumes a table in which the index consists of

FirstName__c

LastName__c

, and

Address__c

<PhoneBook__b> pb = new PhoneBook__b(); pb.FirstName__c = "John"; pb.LastName__c = "Smith"; pb.Address__c = "1 Market St"; pb.PhoneNumber__c = "555-1212";

database.insertImmediate(pb);

pb.Address__c = "1 Market St, San Francisco, CA";

database.insertImmediate(pb);

pb.PhoneNumber__c = "800-555-1212";

database.insertImmediate(pb);

SOQL with Big Objects

You can query the fields in a big object’s index using a subset of standard SOQL commands.

Build an index query starting from the first field defined in the index, without gaps between the first and last field in the query. You can use

, or

. on the last field in your query. Any prior fields in your query can only use the

operator. The

NOT IN

EXCLUDES

, and

INCLUDES

operators are not valid in any query.

The following queries assume that you have a table in which the index is defined by

LastName__c

FirstName__c

, and

PhoneNumber__c

This query specifies all three fields in the index. In this case, the filter on

PhoneNumber__c

can be a range.

SELECT LastName__c, FirstName__c, PhoneNumber__c

FROM Phone_Book__b

WHERE LastName__c='Kelly' AND FirstName__c='Charlie' AND PhoneNumber__c='2155555555'

Big Objects

This query specifies only the first two fields in the index. In this case, the filter on

FirstName__c

can be a range.

SELECT LastName__c, FirstName__c, PhoneNumber__c

FROM Phone_Book__b

WHERE LastName__c='Kelly' AND FirstName__c='Charlie'

This query specifies only the first field in the index. The filter on

LastName__c

can be a range.

SELECT LastName__c, FirstName__c, PhoneNumber__c

FROM Phone_Book__b

WHERE LastName__c='Kelly'

This query doesn’t work because of a gap in the query where

FirstName__c

is required.

SELECT LastName__c, FirstName__c, PhoneNumber__c

FROM Phone_Book__b

WHERE LastName__c='Kelly' AND PhoneNumber__c='2155555555'

Note:

These restrictions do not apply to Async SOQL queries against big objects.

SOQL with Big Objects

CHAPTER 2 Async SOQL

In this chapter ...

•

•

•

Async SOQL is a method for running SOQL queries when you can’t wait for the results in real time. These queries are run in the background over Salesforce entity data, standard objects, custom objects, and big objects. It provides a convenient way to query large amounts of data stored in Salesforce.

EDITIONS

Available in: Enterprise,

Performance, Unlimited, and Developer Editions

Async SOQL is implemented as a RESTful API that enables you to run queries in the familiar syntax of SOQL. Because of its asynchronous operation, you can subset, join, and create more complex queries and not be subject to timeout limits. This situation is ideal when you have millions or billions of records and need more performant processing than is possible using synchronous SOQL. The results of each query are deposited into an object you specify, which can be a standard object, custom object, or big object.

Note: Async SOQL for standard and custom objects is in Pilot.

You can run multiple queries in the background and monitor their completion status. The limit for Async

SOQL queries is two concurrent queries, and a maximum of 10 in a 24-hour period.

Async SOQL Versus SOQL

SOQL and Async SOQL provide many of the same capabilities. So when would you use an Async SOQL query instead of standard SOQL?

Use standard SOQL when:

•

You want to display the results in the UI without having the user wait for results.

•

You want results returned immediately for manipulation within a block of Apex code.

•

You know that the query will return a small amount of data.

Use Async SOQL when:

•

You are querying against millions of records.

•

You want to ensure that your query completes.

•

You do not need to do aggregate queries or filtering outside of the index.

Async SOQL

For example, let’s say that you want to analyze the years and years of opportunity history collected by

Salesforce. The results could help you identify which current and future opportunities are more likely to close and give you a better picture of your forecast. But because the opportunity history data is stored with all the field history data across the application, the volume of data is too large to query directly.

That’s where Async SOQL comes in! You can use it to write a query that extracts a smaller, representative subset of the data that you’re interested. You can store this working dataset in a custom object and use it in reports, dashboards, or any other Force.com feature.

With big objects, you can now bring a much finer level of detail into your applications using data that you already have. For example, every interaction an individual has with your marketing campaign is stored as data that you can use, but it’s unwieldy in its raw form. With Async SOQL, you can aggregate that data by campaign and day, allowing you to extract the relevant details of the full dataset into a

Async SOQL smaller, usable dataset. As in the previous example, the smaller working set can live in a custom object and be used in your reports and dashboards.

Formulating Your Async SOQL Query

To use Async SOQL effectively, it’s helpful to understand its key component and other related concepts. Each query is formulated in the

POST request as a JSON-encoded list of three or four key-value pairs.

Required

Note: When defining the targetFieldMap

parameter, make sure that the field type mappings are consistent. If the source and target fields don’t match, these considerations apply.

•

Any source field can be mapped onto a target text field.

•

If the source and target fields are both numerical, the target field must have the same or greater number of decimal places than the source field. If not, the request fails. This behavior is to ensure that no data is lost in the conversion.

•

If a field in the query result is mapped more than once, even if mapped to different fields in the target object, only the last mapping is used.

Canceling a Query

You can cancel a query using an HTTP DELETE request by specifying its jobId.

https://yourInstance.salesforce.com/services/data/v38.0/async-queries/jobId

Note: Canceling a query that has already completed has no effect.

Handling Errors in Async SOQL Queries

Two different types of errors can occur during the execution of an Async SOQL query.

•

An error in the query execution

•

One or more errors writing the results into the target object

Problems in executing the job cause some errors. For example, an invalid query was submitted, one of the Async SOQL limits was exceeded, or the query caused a problem with the underlying infrastructure. For these errors, the response body includes a status of

Failed. The message parameter provides more information on the cause of the failure.

Other times, the query executes successfully but encounters an error while attempting to write the results to the target object. Because of the volume of data involved, capturing every error is inefficient. Instead, subsets of the errors generated are captured and made available. Those errors are captured in the BackgroundOperationResult object and retained for seven days. You can query this object with the Async SOQL query jobID to filter the errors for the specific Async SOQL query. Async SOQL job info is retained for a year.

Async SOQL Use Cases

Understand some of the common Async SOQL use cases.

Customer 360 Degree and Filtering

In this use case, administrators load various customer engagement data from external sources into Salesforce big objects and then process the data to enrich customer profiles in Salesforce. The goal is to store customer transactions and interactions, such as point-of-sale data, orders, and line items in big objects and then process and correlate that data with your core CRM data. Anchoring customer

Async SOQL Async SOQL Use Cases transactions and interactions with core master data provides a richer 360-degree view that translates into an enhanced customer experience.

The following example analyzes the customer data stored in the Rider record of a car-sharing service. The source big object, Rider_Record_b, has a lookup relationship with the Contact object, allowing for an enriched view of the contact’s riding history. You can see that the query includes Rider__r.FirstName, Rider__r.LastName, Rider__r.Email as part of the

SELECT

clause. This example demonstrates the ability to join big object data (Rider_Record__b) with Contact data (FirstName, LastName, Email) in a single Async SOQL query.

Field Audit Trail

Field Audit Trail lets you define a policy to retain archived field history data up to 10 years, independent of field history tracking. This feature helps you comply with industry regulations related to audit capability and data retention.

You define a Field Audit Trail policy using the

HistoryRetentionPolicy

object for each object you want to archive. The field history data for that object is then moved from the History related list into the

FieldHistoryArchive

object at periodic intervals, as specified by the policy. For more information, see the Field Audit Trail Implementation Guide .

You can use Async SOQL to query archived fields stored in the

FieldHistoryArchive

object. You can use the

WHERE

clause to filter the query by specifying comparison expressions for the

FieldHistoryType

ParentId

, and

CreatedDate

fields, as long as you specify them in that order.

This example queries archived accounts created within the last month.

Example URI

Example POST request body

{

"query": "SELECT ParentId, FieldHistoryType, Field, Id, NewValue, OldValue

FROM FieldHistoryArchive WHERE FieldHistoryType = ‘Account’

AND CreatedDate > LAST_MONTH”,

"targetObject": "ArchivedAccounts__b",

Note: All number fields returned from a SOQL query of archived objects are in standard notation, not scientific notation, as in the number fields in the entity history of standard objects.

Event Monitoring

Login Forensics and Data Leakage Detection, currently in pilot, enable you to track who is accessing confidential and sensitive data in your Salesforce org. You can view information about individual events or track trends in events to swiftly identify unusual behavior and safeguard your company’s data. This feature is useful for compliance with regulatory and audit requirements.

Note: These features are available to select customers through a pilot program. To be nominated to join this pilot program, contact salesforce.com.

In the current pilot, you can monitor data accessed through API calls, which covers many common scenarios because more than 50% of SOQL queries occur using the SOAP, REST, or Bulk APIs. Key information about each query, such as the Username, UserId, UserAgent, and SourceIP, is stored in the ApiEvent object. You can then run SOQL queries on this object to find out details of user activity in your org.

For example, let’s say you want to know everyone who viewed the contact record of your company’s CEO, Jane Doe. The key to this query is the CEO’s contact record ID: 003D000000QYVZ5. (You can also query the ID using SOQL:

SELECT Id FROM Contact

WHERE Name = 'Jane Doe'

). You can use the following Async SOQL query to determine all users who saw their contact information, including when, how, and where they saw it.

Example URI

https://yourInstance—api.salesforce.com/services/data/v38.0/async-queries/

Example POST request body

{

"query": "SELECT Soql, SourceIp, Username, EventTime FROM ApiEvent

WHERE RecordInfo Like '%003D000000QYVZ5%'",

"targetObject": "QueryEvents__c",

"targetFieldMap": {"Soql":"QueryString__c","SourceIp":"IPAddress__c",

"Username":"User__c", "EventTime":"EventTime__c",

"UserAgent":"UserAgent__c"

}

Example POST response body

{

"jobId": "05PB000000001PQ",

"message": "",

"query": "SELECT Soql, SourceIp, Username, EventTime

FROM ApiEvent WHERE RecordInfo Like '%003D000000QYVZ5%'",

Async SOQL Async SOQL Use Cases

"status": "Complete",

"targetObject": "QueryEvents__c",

"targetFieldMap": {"Soql":"QueryString__c","SourceIp":"IPAddress__c",

"Username":"User__c", "EventTime":"EventTime__c", "UserAgent":"UserAgent__c"

}

Note: All number fields returned from a SOQL query of archived objects are in standard notation, not scientific notation, as in the number fields in the entity history of standard objects.

If you ask this question on a repeated basis for audit purposes, you can automate the query using a cURL script.

curl -H "Content-Type: application/json" -X POST -d

'{"query": "SELECT Soql, SourceIp, UserAgent, Username, EventTime FROM ApiEvent WHERE

RecordInfo Like'%003D000000QYVZ5%'","targetObject": "QueryEvents__c",

"targetFieldMap": {"Soql":"QueryString__c", "SourceIp":"IPAddress__c", "Username":"User__c",

"EventTime":"EventTime__c",UserAgent}}'

Another event monitoring use case is to identify all users who accessed a sensitive field, such as Social Security Number or Email. For example, you can use the following Async SOQL query to determine the users who saw social security numbers and the records in which those numbers were exposed.

Example URI

https://yourInstance—api.salesforce.com/services/data/v38.0/async-queries/

Example POST request body

{

"query": "SELECT Soql, Username, RecordIds, EventTime FROM ApiEvent

WHERE Soql Like '%SSN__c%'",

"targetObject": "QueryEvents__c",

"targetFieldMap": {"Soql":"QueryString__c", "Username":"User__c",

Async SOQL Supported SOQL Commands

"EventTime":"EventTime__c", "RecordIds":"Records_Seen__c"

}

"targetObject": "QueryEvents__c"

Supported SOQL Commands

Async SOQL supports a subset of commands in the SOQL language. The subset includes the most common commands that are relevant to key use cases.

Note:

For details of any command, refer to the SOQL documentation .

WHERE

Comparison operators

=, !=, <, <=, >, >=, LIKE

Logical operators

AND, OR

Date formats

YYYY-MM-DD, YYYY-MM-DDThh:mm:ss-hh:mm

Example

SELECT AnnualRevenue

FROM Account

WHERE NumberOfEmployees > 1000 AND ShippingState = ‘CA’

Date Functions

Date functions in Async SOQL queries allow you to group or filter data by time periods, such as day or hour.

Method

DAY_ONLY()

HOUR_IN_DAY()

CALENDAR_MONTH()

CALENDAR_YEAR()

Details

Returns a date representing the day portion of a dateTime field.

Returns a number representing the hour in the day for a dateTime field.

Returns a number representing the month for a dateTime field.

Returns the year for a dateTime field.

Example

SELECT DAY_ONLY(date__c), HOUR_IN_DAY(date__c), count(Id)

FROM FieldHistoryArchive

GROUP BY DAY_ONLY(date__c), HOUR_IN_DAY(date__c)

Async SOQL Supported SOQL Commands

Aggregate Functions

AVG(field), COUNT(field), COUNT_DISTINCT(field), SUM(field), MIN(field), MAX(field)

Note:

MIN()

and

MAX()

do not support picklists.

Example

SELECT COUNT(Id)

FROM FieldHistoryArchive

HAVING

Use this command to filter results from aggregate functions.

Example

SELECT LeadSource, COUNT(Name)

FROM Lead

GROUP BY LeadSource HAVING COUNT (Name) > 100

GROUP BY

Use this option to avoid iterating through individual query results. Specify a group of records instead of processing many individual records.

Example

SELECT COUNT(Id) count, CreatedById createdBy

FROM FieldHistoryArchive

GROUP BY CreatedById

Relationship Queries

Single-level child-to-parent relationships are supported using dot notation. Use these queries with the SELECT, WHERE, and GROUP BY clauses.

Example

SELECT Account.ShippingState s, COUNT(Id) c

FROM Contac

GROUP BY Account.ShippingState
