Question 85/88
Your company is migrating from an on-premises database to a single-region Spanner instance.
The current database supports 40,000 reads each second, and 7,000 writes each second, at 1- KB row sizes at peak. You need to determine the most cost-effective size for the Spanner instance to handle the equivalent current workload. What should you do-
The current database supports 40,000 reads each second, and 7,000 writes each second, at 1- KB row sizes at peak. You need to determine the most cost-effective size for the Spanner instance to handle the equivalent current workload. What should you do-
Correct Answer: A
A single Spanner node (1-000-PU) in a regional SSD configuration can handle up to ~22-500 reads/sec and ~3-500 writes/sec for 1-KB rows. To support 40-000 reads/sec and 7-000 writes/sec, you need at least two nodes (2×22-500-=-45-000 reads; 2×3-500-=-7-000 writes). Of the provided options, a 4-node instance is the smallest choice that exceeds both the read and write requirements, making it the most cost-effective available SKU.
