As organizations grow, so does the volume of their Salesforce data. What starts as a manageable CRM setup can quickly become overwhelming—slowing down system performance, increasing storage costs, and introducing risks related to Salesforce’s governor limits. For both admins and developers, handling large data volumes isn’t just about efficiency; it’s about keeping your org scalable, reliable, and responsive. This guide dives into the most effective strategies to manage large datasets in Salesforce without compromising performance.
Why Large Data Management Matters in Salesforce
Salesforce is built to scale, but even robust systems face strain when data volume goes unchecked. Effective data strategies not only improve system speed but also ensure cleaner reporting, tighter automation, and smarter business decisions.
-
Optimizes Performance: Faster queries and smoother user experiences.
-
Reduces Governor Limit Risks: Less likelihood of hitting system-imposed caps.
-
Improves Reporting and Analytics: Easier to extract insights from organized data.
Data Architecture and Planning
Everything starts with structure. Thoughtful data architecture helps avoid complications down the road.
-
Define Essential Fields: Avoid unnecessary fields—keep only what matters for business logic and reporting.
-
Avoid Excessive Relationships: Use lookup relationships instead of master-detail where possible to reduce processing load.
-
Plan for Data Lifecycle: Strategically archive or delete records no longer in use.
Example: If you’re managing hundreds of thousands of support cases, keep only open and recent cases active, while archiving resolved ones.
Indexing for Faster Retrieval
Indexes are like shortcuts for your queries. Salesforce automatically indexes common fields like Record ID and OwnerID, but you can also request custom indexes on fields frequently used in filters.
Example: If your users frequently search by Region or Product Type, indexing those fields can cut down query times significantly.
Efficient Use of SOQL
Optimizing queries is key to high performance when working with big data.
-
Specify Fields: Never use
SELECT *. -
Use WHERE Clauses: Retrieve only the data you need.
-
Add LIMIT: Always cap large result sets unless a full export is required.
Example:
SELECT Name, Industry FROM Account WHERE Industry = 'Technology' LIMIT 100
This fetches only 100 relevant results instead of scanning the entire Account table.
Optimizing Data Load and Processing
For operations involving thousands of records, use tools like Batch Apex and Data Loader.
-
Batch Apex: Processes data in smaller chunks (e.g., 200 records at a time).
-
Data Loader: Ideal for bulk updates or inserts without user interface delays.
Example: Updating 15,000 records using Batch Apex ensures system stability without hitting governor limits.
Archiving and Deletion Strategy
Outdated or unused records should be offloaded periodically. Use Big Objects for data you rarely access but can’t delete.
Example: Archive closed cases older than 2 years to a Big Object while keeping recent cases active and searchable.
Managing Data Skew
Skew occurs when a single parent (or owner) is linked to too many records.
-
Ownership Skew: Avoid assigning thousands of records to one user.
-
Parent-Child Skew: Limit how many child records are linked to a single parent object.
Example: Distribute ownership of 20,000 accounts across multiple users instead of assigning them all to one service rep.
Asynchronous Processing for Heavy Tasks
For resource-intensive logic, offload operations using:
-
Future Methods: Good for lightweight, delayed tasks.
-
Queueable Apex: Better for chaining jobs or passing complex data.
-
Scheduled Jobs: Useful for off-hours processing like nightly clean-ups.
Example: Use Queueable Apex to send follow-up emails to 10,000 leads after a campaign instead of processing in real-time.
Streamlining Reports and Dashboards
-
Use Filters: Focus reports on relevant data segments.
-
Limit Historical Snapshots: Retain only what’s truly useful.
-
Set Refresh Intervals: Avoid constant, real-time dashboard updates for large datasets.
Example: Filter opportunity reports by the last 3 months instead of pulling all historical data every time.
Externalizing Data
For massive historical datasets or infrequently used records:
-
Use External Objects: Link external systems via Salesforce Connect.
-
Use External Databases: Store raw data externally but reference it when needed.
Example: Store 10+ years of archived sales data in AWS or Azure, and expose it in Salesforce using external objects.
Maintenance and Best Practices
-
Audit Regularly: Review and clean up unused fields, records, and automations.
-
Minimize Data Visibility: Use sharing settings and role hierarchies to restrict access and boost performance.
-
Bulkify Your Code: Always use bulk-safe logic in triggers and Apex.
-
Use Health Check Tools: Regularly scan for security and performance issues.
-
Stay Updated: Leverage new features from Salesforce releases—especially those related to performance and storage.
Conclusion
Managing large data volumes in Salesforce isn’t about quick fixes—it’s about building a system that scales. From the way you query records to how you archive historical data, each choice you make contributes to the performance and reliability of your org. By combining good architecture, smart indexing, asynchronous processes, and regular housekeeping, you’ll be equipped to handle millions of records without slowing down.
