Distributed Databases Questions
Data recovery in a distributed database refers to the process of restoring the database to a consistent and usable state after a failure or error occurs. This involves recovering lost or corrupted data, ensuring data integrity, and bringing the database back online.
Replication in a distributed database involves creating and maintaining multiple copies of the database across different nodes or sites. This is done to improve data availability, fault tolerance, and performance. Replication ensures that data is synchronized and consistent across all copies, allowing for faster access and increased reliability in case of failures.
