Google Cloud Digital Leader Practice Exam

For structured or semi-structured data with a transactional workload and NoSQL, which Google Cloud product is preferred?

1. Digital Native Database

2. Cloud Spanner

3. Firestore

4. Cloud Bigtable

The correct answer is: Firestore

Firestore is well-suited for structured or semi-structured data with a transactional workload in the NoSQL category. It is a flexible, scalable database for mobile, web, and server development. Designed for real-time updates and offline support, Firestore allows developers to easily handle hierarchical data, making it ideal for applications with dynamic data requirements. One of Firestore's key features is its ability to perform transactions and batch writes, which is crucial for maintaining data integrity during concurrent operations. This is particularly important for applications that require data consistency, often seen in transactional workloads. While other options like Cloud Spanner and Cloud Bigtable each serve specific use cases, they cater to different types of workloads. Cloud Spanner excels in SQL transactions over large datasets across multiple nodes, making it best suited for traditional workloads rather than the NoSQL style that Firestore offers. Cloud Bigtable, on the other hand, is optimized for large analytical workloads and does not support complex queries or relationships as efficiently as Firestore does for transactional scenarios. In summary, Firestore’s ease of use in handling transactional workloads, along with its support for real-time data synchronization and offline capabilities, aligns perfectly with the requirements for structured or semi-structured data in a NoSQL environment.
