I’m working with a Salesforce Flow that processes a relatively large number of records, and I’m looking for ways to improve its performance and reliability.
The Flow currently performs several record queries and updates during execution. As the amount of data increases
,the Flow takes longer to complete and can sometimes approach Salesforce governor limits.
What are some recommended approaches for optimizing a Flow in this situation? For example, would reducing Get Records operations, using collections more effectively, or moving some logic to Apex help?
I’d appreciate any practical suggestions or best practices for designing scalable Salesforce Flows.

Hi James,
Optimizing Salesforce Flows for large data volumes is crucial to avoid hitting governor limits (such as CPU time limits, SOQL query counts, and DML limits). Here are the recommended best practices and approaches to scale your flows:
1.Reduce Get Records Operations:Query Optimization.
Avoid placing Get Records or Update/Delete Records elements inside loops. Performing queries or DML operations inside loops quickly exhausts governor limits. Instead, fetch all required data in a single Get Records query
beforethe loop, and store the results in a record collection.
2.Use Collections Effectively:Collection Processing.
Process data in-memory using collection variables and collection filters. Accumulate records that need to be created, updated, or deleted into a collection variable throughout the flow, and perform a single bulk Create, Update, or Delete operation outside of the loop.
3.Move Complex Logic to Apex:Logic Offloading.
If your flow involves complex iterative logic, heavy mathematical calculations, or complex data manipulations that exceed efficient flow capabilities, consider encapsulating that logic within an Invocable Apex action. Apex handles large data volumes and bulk processing much more efficiently and respects governor limits differently.
4.Evaluate Record-Triggered Flow Design:Execution Strategy.
Ensure your record-triggered flows use Fast Field Updates (Before-save) whenever you only need to update fields on the triggering record itself, as these execute significantly faster without triggering additional system overhead. For asynchronous processing, consider utilizing scheduled paths or asynchronous execution when immediate execution isn't strictly required.
