Future-proof your
applications with a no-compromise database
No more relational vs. non-relational. Get high
performance and availability at virtually unlimited scale.
Remove stress from managing databases with zero-touch
maintenance.
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.
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.
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.
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.
Cloud 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.
Strong transactional
consistency
Rely on
industry-leading
external consistency without
compromising on scalability or availability.
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 multi-region instance, your database is
protected against a regional failure and offers
industry-leading 99.999% availability.
Real-time change data
capture and replication
Use
Datastream
to deliver change data from Oracle and MySQL databases into
Spanner for up-to-date information. Use
Spanner change streams
to capture change data from Spanner databases and integrate
it with other systems for analytics, event triggering, and
compliance.
Everything you would
expect from a relational database—schemas, SQL queries, and
ACID transactions—at any scale. Use Google Standard SQL or a
PostgreSQL interface.

How It Works
Cloud 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.
User profile management is a
critical function that requires Spanner's
scalability, availability, and global consistency.
It is the entry point for players across games,
platforms, and regions. Similarly financial
services companies manage customer information and
product offerings using Spanner.
Gain
up-to-date, consistent view of global transactions
Unify financial transactions,
trades, settlements, and positions across the
globe into a consolidated trade ledger built on
Cloud Spanner that guarantees external consistency
and scalability. Consolidation of data helps in
quickly adapting to changing market conditions and
regulatory requirements. Similarly
retail/ecommerce businesses use Spanner for
inventory ledger.
Deliver
always-on interactivity for digital experiences
Consumers expect access to
their critical financial data on their devices
outside of regular banking hours. Allow your
developers to focus on new experiences rather than
operational overhead, such as manual sharding or
eventual consistency. Reduce risk and downtime
with 99.999% availability and zero maintenance.
Track customer participation
and preferences in a loyalty program to analyze
trends and improve customer satisfaction.
Similarly, game companies use Spanner for building
personalized leaderboards in games.
Provide a
consistent view across multiple channels and apps
Spanner provides a high
performance, single source of truth for retail
inventory and orders across online, in-store,
distribution centers, and shipping to match
inventory with demand, improving customer
experience and profitability. Game companies
similarly use Spanner to store in-game inventory
data.
Spanner pricing is
based on compute capacity, database storage, backup
storage, and network usage. Committed use discounts reduce
the price further.

FAQ
Cloud Spanner 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.
Cloud 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 Cloud Spanner PostgreSQL
interface, see
our documentation.
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
HarbourBridge
for Schema and Data migration, and third party
tools for assessments like migVisor. Learn more
about the migration process in
our documentation.
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.
