Globally Distributed Database | Oracle

Oracle Globally Distributed Database is a single logical database that automatically distributes and replicates data across various nodes, regions, and countries. It helps organizations build always-on architectures and achieve high performance while addressing data residency requirements. Applications can use Oracle Database’s AI and converged capabilities, strong consistency, and full SQL support without code changes. Globally Distributed Database is available as automated services in Oracle Cloud Infrastructure (OCI), as well as part of multicloud and on-premises Oracle Database deployments.

Enable rapid failover within seconds and help eliminate data loss during outages with Raft replication and an Active-Active-Active distributed database architecture that’s designed for mission-critical applications.

Reduce performance bottlenecks with independent and granularly scaled database compute, storage capacity, and data ingest rates for AI, transaction processing, and analytics.

Help meet data residency requirements by implementing automated data distribution and access policies for data, replicas, backups, and encryption keys based on geography.

All shards are presented to an application and administered as a single logical database, simplifying application development and database administration. Oracle Database workloads and data types that are supported include relational, AI vector, JSON, Graph, and Spatial.

Choose from more data distribution and replication methods than other leading distributed databases to more easily address diverse application and business requirements.

Use Globally Distributed Autonomous Database and Globally Distributed Exadata Database on Exascale Infrastructure in OCI, Oracle Database services on OCI in multicloud environments, and Oracle Database Enterprise Edition in customer data centers.

Six data distribution methods enable applications to optimally collocate data to address needs for low latency, high performance, extreme availability, data residency, and other criteria.

• Data is automatically placed on the desired shard, saving time and eliminating manual rebalancing
• Composite sharding, which allows two levels of sharding with different sharding methods and keys
• Parallel data ingestion on all shards
• Parallel queries across all shards
• Select through the console on cloud services

Handle peak workloads for agentic AI and hyperscale OLTP performance by scaling compute, memory, and storage independently on Distributed Exadata Database on Exascale Infrastructure.

• Near-instant online addition and deletion of database nodes on Exascale Infrastructure
• No data copying when adding nodes on Exascale Infrastructure
• Decoupled compute and storage with Exascale
• Automated redistribution of data
• Automatic shard rebalancing

A built-in shard catalog allows all shards in Globally Distributed Database be managed as a single, logical database. Cloud services implement centralized administration through the cloud console.

• Sharded database configuration, including data distribution policies and the addition or removal of shards
• High availability configuration using a choice of replication methods and custom replication topologies, including by geography or application tier
• Database object management—simplified operations at scale via seamless integration with Oracle Enterprise Manager, OCI console, and automation frameworks
• Backup and recovery
• Security configuration

Oracle Globally Distributed Database is natively supported by Oracle Database client drivers. Developers can treat Globally Distributed Database as a single logical database, simplifying application development.

• Automated request routing to shards
• Automated routing of multishard requests to coordinator
• Transaction support for multishard updates
• Support for JDBC, OCI, .Net drivers
• Automated failover to standbys
• Support for FAN events
• Automatic identification of sharding key (21 JDBC)

Oracle Globally Distributed Database helps protect against unplanned outages and provides online mechanisms for planned administrative and maintenance operations, enabling applications to offer always-on availability.

• Choice of automated replication technologies including Raft
• Automated failover
• Fault isolation
• Online patching and upgrade
• Backup and recovery
• Disaster protection

Oracle Globally Distributed Autonomous Database combines the shared-nothing scalability, data locality management, and extreme availability of a distributed database with the full automation of Oracle Autonomous Database. It helps customers meet data residency requirements, provide survivability for business-critical applications, and deliver cloud-scale database performance.

• Uses Autonomous Database’s self-managing, self-tuning, and self-scaling of nodes to reduce administrative overhead.
• Runs on Dedicated Exadata Infrastructure for enhanced isolation and security.
• Simplifies management with automatic data distribution, automated application routing and centralized administration.

Oracle Globally Distributed Exadata Database on Exascale Infrastructure delivers extreme availability, performance, and scalability for any type of Oracle Database workload. Each location uses pools of shared database-optimized compute and storage resources that enable performance scaling without copying data. It lets organizations minimize costs with small—yet powerful—configurations, granular elastic scaling, and pay-per-use economics.

• Deployed on secure and highly scalable multitenant resources.
• Independently scale database compute and storage—without downtime.
• Console-based automation helps automate data distribution, replication, resource scaling, and online maintenance

Oracle Databases on OCI offer built-in access to globally distributed database capabilities. Existing Oracle Database applications can start using a distributed database without modifications. Consumption of database server licenses can be scaled up or down at any time without downtime, enabling users to optimize performance while reducing costs.

• Oracle Globally Distributed Database can be used with Oracle Database Release 19c or 23ai to gain Raft replication.
• Works with existing Oracle Exadata Database Service and Base Database Service environments.
• Provides administrator-based management of data distribution and replication.

Use Globally Distributed Database capabilities built into Oracle Database Enterprise Edition wherever it’s deployed. Deploy databases that span OCI, AWS, Azure, and Google Cloud to expand beyond the boundaries of any single cloud.

• Run Oracle Database Enterprise Edition deployed at Oracle Database multicloud partners.
• Each multicloud location provides low latency access to hyperscaler-specific services, tooling, and infrastructure.
• Use Oracle Database 23ai to access Raft replication.

Use Globally Distributed Database capabilities built into Oracle Database Enterprise Edition wherever it’s deployed. Deploy databases that span OCI, AWS, Azure, Google Cloud, and your data centers to deploy closer to customers or in locations without cloud data centers.

• Works as part of Oracle Databases deployed at Oracle Database multicloud partners.
• Provides low latency access to hyperscaler-specific services, tooling, and infrastructure.
• Leverage Exadata Database Machine, Exadata Cloud@Customer, Oracle Database Appliance, or non-Oracle infrastructure in your data center.

Keep your data in your data center to help you meet data residency mandates, network latency, or high-throughput ingest requirements. Oracle Globally Distributed Database can be deployed on self-managed platforms or on Oracle-managed Exadata Cloud@Customer infrastructure wherever you need it.

Oracle offers the following choices for on-premises deployments of Globally Distributed Database:

• Exadata: On-premises
• Exadata: Cloud@Customer
• Oracle Database Appliance
• Non-Oracle infrastructure

“With the introduction of built-in RAFT-based replication, the new release brings the concept of database sharding to a new level of scalability and performance. A global, hyperscale database that is distributed and replicated across multiple geographical locations in real time is now a reality—and the data within it can be transparently localized according to complex rules.”

Alexei Balaganski
Lead Analyst and Chief Technology Officer, KuppingerCole Analysts

“Deploying successful agents with transactional systems is hard. With its scaling capacity, Oracle Globally Distributed Database on Exascale gives enterprises the capacity headroom so they can be confident they can scale in the AI era.”
