ORACLE 19C SHARDING: A COMPREHENSIVE GUIDE TO MODERN DATA DISTRIBUTION

ABSTRACTOracle 19C Sharding is a new feature that represents a data management capability that empowers users to the arrangement of one database spread across a collection of databases (shards). They do not have hardware or software systems in place for this method. Enhancing scalability and availability while ensuring disaster recovery on a scale is crucial for mission critical applications by dividing data into smaller fragments which makes it easy to handle. Oracle 19c Sharding enhances reliability by minimizing the chance of bottlenecks and vulnerabilities in a system. Oracle Sharding supports global and local transactions which ensures data consistency and maintains integrity throughout the database across all the shards. The key features of Oracle 19c Sharding are automatic shard management, multi-shard queries and seamless integration to other high availability technologies like Data Guard, Golden- Gate and Real Application clusters. By implementing database sharding, organizations can get benefits of greater performance, flexibility and scalability from the database environment.
