Over the last four years, the Oracle Database Development team has diligently worked to deliver the next long-term support release: Oracle Database 23ai, with a focus on AI and enhancing developer productivity.

Today, we are thrilled to announce support for Oracle Database 23ai on the Oracle Globally Distributed Autonomous Database!. Oracle Database 23ai, in conjunction with the Oracle Globally Distributed Autonomous Database, is a game-changer for enterprises worldwide seeking to build cloud-scale distributed databases with ultra-high scalability, availability, and advanced AI capabilities.

With the latest release, Oracle Globally Distributed Autonomous Database allows customers to select their preferred replication strategy to ensure high availability and disaster recovery. You can choose between the new built-in Raft replication (introduced in 23ai) and Oracle Data Guard (available in releases 19c and 23ai). The service automatically deploys the specified replication topology to the configured systems and enables seamless data replication. If you are used to NoSQL databases and do not expect to know anything about how replication works, Globally Distributed Autonomous Database built-in Raft replication just works.

Key benefits for Raft replication include:

Fast failover with zero data loss: Raft replication is built into Globally Distributed Autonomous Database to provide a consensus-based, high-performance, low-overhead availability solution, with distributed replicas and fast failover with zero data loss, while automatically maintaining the replication factor if shards fail.

Active-Active symmetric configuration : Each node accepts writes and reads for a subset of data facilitating an Active-Active symmetric distributed database architecture that enhances availability, and optimizes resource utilization globally.

Simplified management: Raft replication is integrated and transparent to applications without requiring configuration of Oracle GoldenGate or Oracle Data Guard. Raft replication automatically reconfigures replication in case of shard host failures or when shards are added or removed from the sharded database.

Automatic data distribution: The service handles workload distribution and balancing upon scaling (addition or removal of shards), including planned or unplanned changes in shard availability. 

By supporting Oracle Database release 23ai, Globally Distributed Autonomous Database offers customers enhanced replication options and advanced AI capabilities including Select AI and AI Vector Search. It provides all of the new benefits on top of 23ai including unparalleled flexibility, improved operational efficiency, enhanced performance, simplified scalability, and compliance for modern applications. Stay tuned for more updates and detailed guides on leveraging these new capabilities to maximize your database’s potential.
