Distributed Databases

In environments where databases are distributed for data residency, global scalability, performance, and availability, GDS acts as an intelligent traffic director and workload coordinator.

Oracle Global Data Services (GDS) provides the following management capabilities:

• Shard Director and Shard Catalog: GDS acts as a "shard-aware" proxy, intercepting client requests and routing them to the appropriate shard containing the relevant data.
• Data Locality: GDS ensures that requests are directed to the shard where the data resides, minimizing data movement and optimizing performance.
• Scalability and Parallelism: GDS facilitates scaling out the database by adding more shards, and it can leverage parallel query capabilities to improve query performance.
• Simplified Application Development: GDS hides the complexity of the sharding scheme from applications, allowing them to interact with the database as a single logical unit.

Distributed Databases Example Use Cases

• Global E-commerce Platforms: Stores product data across multiple regions to provide low-latency access to users worldwide.
• Social Media Networks: Distributes user profiles, posts, and media across geographically dispersed nodes, improving scalability and response time.
• Financial Services: Manages transactions and customer data across multiple regions while ensuring consistency and high availability.
• Content Delivery Networks (CDNs): Distributes large datasets, like videos and images, across various data centers to optimize content delivery to end-users.
• IoT Applications: Processes real-time data from sensors distributed globally, requiring local processing and centralized analytics.
