Google Cloud Professional Data Engineer PDE — Topic 1 Question 93

Question

You're using Bigtable for a real-time application, and you have a heavy load that is a mix of read and writes. You've recently identified an additional use case and need to perform hourly an analytical job to calculate certain statistics across the whole database. You need to ensure both the reliability of your production application as well as the analytical workload. What should you do?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Add a second cluster to an existing instance with a single-cluster routing, use live-traffic app profile for your regular workload and batch-analytics profile for the analytics workload. Google Cloud Batch schedules and runs batch jobs at scale without managing infrastructure. This option meets the real-time / low-latency performance requirement.
