• Automatic Replication and Failover

Use Cases

Google Cloud Spanner is suited for various applications, including:

1. Large-scale transaction processing systems
2. Gaming applications with high availability
3. Financial applications requiring strong consistency
4. Global applications needing low-latency access

Getting Started

Follow these steps to set up Google Cloud Spanner:

                graph LR
                    A[Create Google Cloud Project] --> B[Enable Spanner API]
                    B --> C[Create Spanner Instance]
                    C --> D[Create Database]
                    D --> E[Create Tables]
                    E --> F[Insert Data]
                    F --> G[Query Data]
            

                // Example: Creating a Spanner instance in Go
                package main

                import (
                    "context"
                    "cloud.google.com/go/spanner"
                    "log"
                )

                func main() {
                    ctx := context.Background()
                    client, err := spanner.NewClient(ctx, "projects/my-project/instances/my-instance/databases/my-database")
                    if err != nil {
                        log.Fatalf("Failed to create client: %v", err)
                    }
                    defer client.Close()
                }
