Lesson: 14 | How can you ensure that a Flow is bulk-safe in Salesforce?

Notes

Notes

To ensure a Flow is bulk-safe, you must design it to handle multiple records efficiently while staying within Salesforce governor limits. Here are the key practices:

1. Minimize SOQL and DML Operations

Use Get Records and Update Records elements outside loops to avoid hitting SOQL and DML limits.
Use Collection Variables to group records and perform bulk operations in a single step.

2. Use Bulk-Safe Elements

Prefer using elements that inherently support bulk processing, such as Fast Field Updates and Fast Record Lookup in certain Flow types.

3. Optimize Loops

Avoid performing DML or SOQL operations inside loops. Instead, collect the data in a variable during the loop and perform a single bulk operation afterward.
For example, in a Flow iterating through records, gather IDs into a collection and update them all at once after the loop.

4. Test with Bulk Data

Test the Flow with a large number of records to simulate real-world scenarios and identify potential bulk-processing issues.

5. Handle Errors Gracefully

Implement Fault Paths to handle errors and avoid Flow termination when processing bulk records.

6. Check Governor Limits

Keep an eye on Salesforce governor limits, such as:
- 100 SOQL queries per transaction.
- 150 DML statements per transaction.
- 200,000 CPU time limit in synchronous Flows.

7. Leverage Apex Where Needed

If a Flow's logic becomes too complex or risks breaching governor limits, consider offloading certain parts to an invocable Apex class, which can handle bulk processing more efficiently.
