In a recent blog post, Google announced a slew of new features for Cloud Spanner. The public cloud provider released the service with new updates including the managed backup-restore feature, foreign key support, query optimizer versioning feature, a C++ client library, and a local emulator.
Cloud Spanner is a globally distributed, scalable, multi-version database service on the Google Cloud Platform (GCP). Since its inception, Google keeps evolving the database service since its beta with updates such as updates to its data manipulating (DML) SQL language, and new regions, and multi-region configurations.
