Features
Write and read scalability with no limits
Spanner decouples compute resources from data storage, which makes it possible to transparently scale in and out processing resources. Each additional compute capacity can process both reads and writes, providing effortless horizontal scalability. Spanner optimizes performance by automatically handling the sharding, replication, and transaction processing.
Automated maintenance
Reduce operational costs and improve reliability for any size database. Synchronous replication and maintenance are automatic and built in. 100% online schema changes and maintenance while serving traffic with zero downtime.
Spanner Graph
Reveal hidden relationships and connections. Spanner Graph supports ISO Graph Query Language (GQL), the new international standards for graph databases, offering an intuitive and concise way to match patterns and traverse relationships in your data. It combines the strengths of SQL and GQL, enabling you to query structured and connected data in a single operation. Spanner Graph, in Preview, interoperates with full-text and vector search capabilities, enabling you to deliver a new class of AI-enabled applications.
Vector search
Search vector embeddings at virtually unlimited scale in Spanner with exact nearest neighbor (KNN) and approximate nearest neighbor (ANN) vector search (both in Preview) for highly partitionable workloads. The built-in vector search support in Spanner eliminates the need for separate, specialized vector database solutions, providing transactional guarantees of operational data, fresh and consistent vector search results on a scale-out serverless architecture with zero manageability.
PostgreSQL interface
Combine the scalability and reliability of Spanner with the familiarity and portability of a PostgreSQL interface. Use the skills and tools that your teams already know, future-proofing your investment for peace of mind.
Automatic database sharding
Never worry about manually resharding your database again. Built-in sharding automatically distributes data to optimize for performance and availability. Scale up and scale down without interruption.
Geo-partitioning
Retain the manageability of your single, global database while improving latency for users who are distributed around the globe. Geo-partitioning in Spanner allows you to partition your table data at the row level, across the globe, to serve data closer to your users. Even though the data is split into different data partitions, Spanner still maintains all your distributed data as a single cohesive table for queries and mutations.
Single-region, dual-region, and multi-region configurations
No matter where your users may be, apps backed by Spanner can read and write up-to-date strongly consistent data globally. Additionally, when running a dual-region or multi-region instance, your database is protected against a regional failure and offers industry-leading 99.999% availability.
Strong transactional consistency
Rely on industry-leading external consistency without compromising on scalability or availability.
High-performance, workload-isolated query processing
Spanner Data Boost enables users to run analytical queries, batch processing jobs, or data export operations faster without affecting the existing transactional workload. Fully managed by Google Cloud, Data Boost does not require capacity planning or management. It is always hot, ready to process user queries directly on data stored in Spanner's distributed storage system, Colossus. This on-demand, independent compute resource lets users easily handle mixed workloads and worry-free data sharing.
Full-text search
Eliminate separate search tools and associated extract, transform, and load (ETL) pipelines by utilizing high-performance text search powered by learnings from Google Search. Full-text search provides transactionally consistent search results, along with powerful capabilities such as phonetic search, and NGRAMs-based matching for spelling variations.

LangChain integration
Easily build gen AI applications that are more accurate, transparent, and reliable with LangChain integration. Spanner has three LangChain integrations—Document loader for loading and storing information from documents, Vector stores for enabling semantic search, and Chat Messages Memory for enabling chains to recall previous conversations. Visit the GitHub repository to learn more.
Vertex AI integrations
Perform online inference on embedding, generative AI, or custom models served in Vertex AI using Spanner’s ML.PREDICT SQL function. Use the Spanner to Vertex AI Vector Search Workflow to perform similarity search on your Spanner data with Vertex AI Vector Search.
Enterprise-grade security and controls
Customer-managed encryption keys (CMEK), data-layer encryption, IAM integration for access and controls, and comprehensive audit logging. Support for VPC-SC, Access Transparency, and Access Approval. Fine-grained access control lets you authorize access to Spanner data at the table and column level.

How It Works
Spanner instances provide compute and storage in one or more regions. A distributed clock called TrueTime guarantees transactions are strongly consistent even across regions. Data is automatically "split" for scalability and replicated using a synchronous, Paxos-based scheme for availability.

FAQ
Is Spanner a relational or non-relational database?
Spanner simplifies your data architecture by bringing together relational, key-value, graph, and vector search workloads—all on the same database. It is a highly scalable database that combines unlimited scalability with relational semantics, such as secondary indexes, strong consistency, schemas, and SQL providing 99.999% availability in one easy solution. Hence, it’s suitable for both relational and non-relational workloads.
Does Spanner use SQL?
Spanner provides two ANSI-based SQL dialects over the same rich set of capabilities: GoogleSQL and PostgreSQL. GoogleSQL shares syntax with BigQuery for teams standardizing their data management workflows. The PostgreSQL interface provides familiarity for teams who already know PostgreSQL and portability of schemas and queries to other PostgreSQL environments. For more information about the Spanner PostgreSQL interface, see our documentation.
How do I migrate databases to Spanner?
Migration to Spanner can vary widely depending on a number of factors like source database, data size, downtime requirements, application code complexity, sharding schema, custom functions or transformations, failover and replication strategy. The recommended tooling comprises open source tools like Spanner migration tool for schema and data migration, and third party tools for assessments like migVisor. Learn more about the migration process in our documentation.
What are the key considerations for operating Spanner?
Spanner is a fully managed database so it automatically provides comprehensive infrastructure management features, but there are some application-specific management actions that may be required depending on your workload. You will need to make sure that you have set up proper alerting and monitoring and that you are watching those closely to ensure production is always running smoothly. You need to understand what actions to take when traffic grows organically over time, or if there is peak traffic expected, or how to handle data corruption due to application bugs, and last but not least, how to troubleshoot performance issues and understand what components are responsible for increased latencies.
