Explain the concept of data replication in distributed databases. What are the challenges associated with data consistency in a replicated environment, and how can they be addressed?
Explain the concept of data replication in distributed
Data replication, in distributed databases involves duplicating data across nodes or locations within a distributed database system.
This redundancy serves purposes, such as enhancing data availability fault tolerance and performance.
The main goals of data replication are.
1. High Availability: By supporting copies of data the system can continue to function even if certain nodes or data centers become inaccessible due to network issues or hardware failures.
2. Load Balancing: Distributing data across nodes helps distribute query loads and improves system performance by reducing bottlenecks.
3. Reduced Latency: Storing data closer to where it is needed reduces data access latency for users or applications in geographic regions.
