Spanner is Google's fully managed, globally distributed database with high throughput and virtually unlimited scale. Spanner processes over 4 billion queries per second at peak. With features such as automatic sharding, zero downtime, and strong consistency, Spanner powers demanding, global workloads - not only across customers in financial services, gaming, retail, and other industries but also Google internally - that are both relational and non-relational.

Previously, to maintain data residency in countries with only two Google Cloud regions, you were restricted to regional Spanner configurations with 99.99% availability. That's because Spanner multi-region configurations require three regions, one of which would be located outside the country. You can now take advantage of Spanner's industry-leading 99.999% availability while complying with data residency requirements using the new Spanner dual-region configurations. The new dual-region configurations - now available in Australia, Germany, India, and Japan - help ensure your data resides within the selected country.
