Globally Distributed Database

Oracle Globally Distributed Database disperses segments of a data set across many databases (shards) onto different computers—on-premises or in the cloud. It enables globally distributed, linearly scalable, multimodel databases. It requires no specialized hardware or software. Oracle Globally Distributed Database does all this while rendering the strong consistency, full power of SQL, support for structured and unstructured data, and the Oracle Database ecosystem. It meets data sovereignty requirements and supports applications that require low latency and high availability.

RAFT Replication

RAFT Replication enables rapid failover within seconds and zero data loss during node or data center outages, facilitating an Active-Active-Active symmetric distributed database architecture that enhances availability, simplifies management, and optimizes resource utilization globally.

RAFT Replication in Oracle Globally Distributed Database

Data lake

Oracle Database is a converged database. It can store relational data and other types of unstructured or semistructured data, such as text, JSON, Graph, and Spatial. Oracle Globally Distributed Database can be used to store massive amounts of structured and unstructured data and to eliminate data fragmentation.

Globally Distributed Database features

Automated data distribution

Automated sharding and resharding of data

Oracle Globally Distributed Database automatically places data on the desired shard, saving time and eliminating manual data preparation.

  • Multiple sharding methods (system-managed and user-defined)
  • Composit sharding, which allows two levels of sharding with different sharding methods and keys
  • Parallel data ingestion on all shards
  • Parallel queries across all shards


Flexible sharding based on your needs

Shards can be added and removed and data can be resharded without any downtime or data loss.

  • Online addition and removal of shards
  • Automated resharding of data

Centralized administration

Centrally manage and monitor sharded databases as a single logical database

A shard catalog allows you to manage all shards in Globally Distributed Database as a single, logical database.

  • Setup and configuration of the sharded database
  • Addition and removal of shards
  • High-availability configuration
  • Database object management
  • Patching of shards
  • Detailed monitoring metrics
  • Security configuration

Automated application routing

Simplified application development

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)

High availability

Zero unplanned or planned downtime

Oracle Globally Distributed Database has protection from unplanned outages and provides mechanisms for online planned operations, enabling applications to meet stringent availability SLAs.

  • Automated data replication
  • Automated failover
  • Fault isolation
  • Online patching and upgrade
  • Backup/recovery
  • Disaster protection
  • RAFT replication

Oracle Globally Distributed Database makes sharding seamless

Globally Distributed Database offers a seamless and efficient solution to accommodate a global user base and navigate diverse data regulations.

Easy administration

Globally Distributed Database presents all the shards as a single logical database. The centralized administration, managed through a shard catalog, offers a comprehensive view of the distributed database as a cohesive unit, minimizing complexities.

Simplified operations

Manual data sharding is eliminated with automatic data distribution, simplifying deployment by incorporating automatic sharding and resharding capabilities.

Streamlines application development

Automated routing capability streamlines application interfaces with the database as a unified logical entity and offers native support for database client drivers.

What customers are saying about Oracle Globally Distributed Database

“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

“Oracle yet again raised availability and scalability SLAs for mission-critical applications by introducing RAFT replication with its Globally Distributed Database 23ai. It clearly sets the new industry standard for enterprises.”
