Spanner vs. Traditional SQL/NoSQL

Spanner introduction● Global Scale

Horizontally scalable across regions and data centers, from 1 to hundreds or thousands of nodes

● Fully ManagedDatabase management service means replication and maintenance are automatic

● Relational SemanticsEverything you would expect from a relational database - schemas, ACID transactions, and SQL queries (ANSI 2011)

● Multi Language SupportClient libraries in Java, Go, Python, Node.js and more coming. JDBC driver for connectivity with popular third-party tools

Spanner introduction● Transactional Consistency

Purpose built for strong, global transactional consistency

● Enterprise Grade SecurityData-layer encryption, IAM integration for access and controls, and audit logging

● Highly AvailableWhenever, wherever, your data is highly available

Interactive with Cloud Console

Performance guidance● Each Spanner node can provide up to 10,000 QPS of reads or 2000 QPS

of writes (writing single rows at 1KB data per row), and 2 TiB storage.● For optimal performance, we recommend provisioning enough nodes to

keep overall CPU utilization under 75%.● Minimum of 3 nodes recommended for production environments.● Note that Cloud Spanner performance is highly dependent on workload,

schema design, and dataset characteristics. The performance numbers above are estimates, and assume best practices are followed.
