JencoMart wants to move their User Profiles database to Google Cloud Platform. Which Google Database should they use?

Google Cloud Datastore is a highly scalable NoSQL document database, ideal for storing user profiles due to its flexibility with schema-less data and automatic scaling. Cloud Spanner is a globally distributed relational database, offering strong consistency and high availability, but it's often overkill for simple user profiles and more suited for transactional workloads requiring strict ACID compliance across regions. Google BigQuery is an analytical data warehouse designed for large-scale data analysis, not operational transactional data like user profiles. Google Cloud SQL is a fully managed relational database service for MySQL, PostgreSQL, and SQL Server, which could work but might require more schema management and scaling effort compared to Datastore for this specific use case.
