Exam Professional Cloud Database Engineer topic 1 question 83 discussion

Scheduler + CF

Minimal Cost Approach: 1. Put the python script on the Cloud Function 2. Schedule weekly trigger using Cloud Scheduler Compute Engine and Cloud Composer would increase the cost and making it complex

C. Need to automate and minimize costs/overhead. Eliminate A. From Google’s documentation, “Cloud Composer is a fully managed workflow orchestration service, enabling you to create, schedule, monitor, and manage workflow pipelines that span across clouds and on-premises data centers.”. We don’t need Cloud Composer. Eliminate B. To have something run at a specific time on a specific schedule, you need to use Cloud Scheduler (which has cron like scheduling). Cloud Tasks doesn’t do that. Eliminate D. That leaves C.

C Cloud Scheduler triggers actions at regular fixed intervals, whereas Cloud Tasks triggers actions based on how the individual task object is configured. Reference: https://cloud.google.com/tasks/docs/comp-tasks-sched

I'll go for C

C: Create a Cloud Function, and call the Cloud Function using Cloud *** Scheduler. Compare Cloud Tasks vs. Cloud Scheduler Both Cloud Tasks and Cloud Scheduler can be used to initiate actions outside of the immediate context. But they have significant differences in functionality and usage. This page helps you understand the differences between them.
