SNOW-CAD Platform Features and Integration Practice Question
An organization has a ServiceNow instance that integrates with an external HR system using a scheduled job that runs every hour. The job uses a REST message to fetch new hire records and creates user accounts in ServiceNow via a transform map. Recently, the number of new hires has increased significantly, and the job now takes over an hour to complete, causing the next job to start before the previous one finishes. The administrator notices that the transform map is using 'Coalesce' set to 'false' because the external system does not provide a unique identifier. The job also creates a large number of intermediate records that are later updated. The administrator wants to optimize the process to prevent overlapping job runs. Which course of action should the administrator take?
⚠ Common exam trap
Watch out — candidates often assume increasing the interval or adding parallelism (Options A or D) will solve the overlap, but they overlook that without a unique identifier, parallel processing can cause duplicates, and simply delaying the job does not fix the underlying processing speed issue.
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
✓
Set the 'Maximum rows to load' property on the transform map to a value that ensures the job finishes within 60 minutes
Setting the 'Maximum rows to load' property on the transform map limits the number of rows processed per run, ensuring the job completes within the 60-minute window. This prevents overlapping runs by capping the workload, allowing the scheduled job to finish before the next trigger, without requiring changes to the integration logic or external system.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the scheduled job's interval to run every 2 hours to avoid overlap
Why it's wrong here
This only delays the overlap; if the job still takes >2 hours, the problem recurs.
- ✓
Set the 'Maximum rows to load' property on the transform map to a value that ensures the job finishes within 60 minutes
Why this is correct
Limiting the rows per run controls the job duration, preventing overlap.
- ✗
Change the transform map to run asynchronously using a flow triggered by the import set row
Why it's wrong here
Asynchronous processing still puts all rows into the queue; the job will still take the same time to load all rows.
- ✗
Configure the import set table loader to run in multiple parallel threads to process records faster
Why it's wrong here
Parallel threads may cause race conditions and increased server load, and do not guarantee the job finishes within the window.
