Handling Bulk Data in Salesforce
In business, organizations manage large volumes of customer and transactional data. Salesforce, as a cloud-based customer relationship management platform, is designed to support this scale. However, it enforces certain usage limits to maintain system stability and fairness.
This is where bulk data handling becomes essential. For Salesforce developers, administrators, and data professionals, understanding how to process records in efficient and controlled batches is key to maintaining performance and avoiding system errors. If you are aiming to build or upgrade your skills in this area, enrolling in a Salesforce Course Online can provide the practical knowledge and tools.
Why Bulk Data Handling Matters
Salesforce operates on a multitenant architecture, meaning that multiple customers share the same computing resources. To ensure that the performance remains consistent and no single user impacts others, Salesforce enforces strict governor limits. These include limits on the number of records that can be queried, inserted, or updated within a single transaction.
If you don’t design your logic to handle bulk data, you may encounter issues like:
- CPU time limit exceeded
- Too many SOQL queries
- Too many DML rows
- Heap size limits
Key Tools for Bulk Data Management
1. Batch Apex
When you need to process thousands (or even millions) of records, Batch Apex is your go-to tool. It splits large data into manageable chunks and processes each batch separately.
Example:
global class AccountBatchClass implements Database.Batchable<sObject> {
global Database.QueryLocator start(Database.BatchableContext BC) {
return Database.getQueryLocator(‘SELECT Id, Name FROM Account’);
}
global void execute(Database.BatchableContext BC, List<Account> scope) {
for(Account acc : scope){
acc.Name += ‘ – Verified’;
}
update scope;
}
global void finish(Database.BatchableContext BC) {
System.debug(‘Batch processing complete.’);
}
}
This method is ideal for data cleansing, mass updates, or scheduled operations.
2. Bulk API
Salesforce’s Bulk API allows you to load or delete massive amounts of data asynchronously. It is particularly useful for integrations with external systems where speed and scale are priorities.
You can use tools like Workbench, Postman, or automation platforms to interact with the Bulk API.
3. Data Loader
For manual operations like mass inserts, updates, or deletions, Salesforce Data Loader is a widely used tool. It supports both GUI and command-line operations and is ideal for admins or analysts handling CSV files.
Governor Limits Safe Coding Practices
To make your code bulk-safe:
- Avoid SOQL or DML statements inside for loops.
- Use collections like Lists, Sets, and Maps to batch process records.
- Implement error handling and partial commits in case of failures.
- Use @future or Queueable Apex for background processing.
Example: Data Clean-Up Operation
Let’s say your company has thousands of leads that need to be flagged based on specific criteria. Instead of writing a script that processes each record individually, use Batch Apex with a bulk-safe approach:
if (!Trigger.isBulk) {
// NOT recommended
update new Lead(Status = ‘Reviewed’);
} else {
// Bulk-safe
List<Lead> leadsToUpdate = new List<Lead>();
for (Lead ld : Trigger.new) {
if (ld.Industry == ‘Retail’) {
ld.Status = ‘Reviewed’;
leadsToUpdate.add(ld);
}
}
update leadsToUpdate;
}
