A developer needs to update a large number of records in the 'incident' table based on a specific condition. Which approach should be used to minimize performance impact?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use GlideRecord with setWorkflow(false) and setEngine(false) to update records in a loop.
A is correct because using GlideRecord with setWorkflow(false) and setEngine(false) prevents unnecessary business rules and workflow execution, reducing performance impact. B is incorrect because GlideAggregate is used for aggregation and statistics, not for updating records. C is incorrect because an export set is designed for data export/import, not for bulk updates within the platform. D is incorrect because updateMultiple does perform bulk updates but still triggers business rules if not disabled, and it does not provide the same level of control as GlideRecord with disabled workflows.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use GlideRecord with setWorkflow(false) and setEngine(false) to update records in a loop.
Why this is correct
Using GlideRecord with setWorkflow(false) and setEngine(false) prevents business rules and workflow execution, reducing overhead.
- ✗
Use GlideAggregate to perform the update.
Why it's wrong here
GlideAggregate is for aggregation, not updates.
- ✗
Use an export set to update records in bulk.
Why it's wrong here
Export set is used for data export/import, not for bulk updates.
- ✗
Use the updateMultiple method on a GlideRecord object.
Why it's wrong here
updateMultiple can be efficient but still triggers business rules if not disabled, offering less control than GlideRecord with disabled workflows.
