Distributed Databases Questions
Data availability refers to the ability of users to access and retrieve data from a distributed database system. It ensures that data is accessible and usable whenever it is needed, without any interruptions or delays.
Replication, on the other hand, is the process of creating and maintaining multiple copies of data across different nodes or sites in a distributed database. These copies are synchronized to ensure consistency and provide redundancy. Replication improves data availability by allowing users to access data from multiple locations, even if one or more nodes are unavailable or experiencing issues. It also enhances fault tolerance and improves performance by reducing network latency.
