Answer: Cloud Spanner
Cloud Spanner is the recommended choice because it is a globally distributed relational database that offers strong consistency and SQL support, making it ideal for mission-critical applications like inventory management. Unlike Cloud SQL, which is limited to a single region, Cloud Spanner can scale horizontally across multiple regions. Cloud Firestore lacks SQL support, and BigQuery is designed for data warehousing, not for OLTP systems such as inventory management.
